Difference Between A Direct Fit And A Universal Fit For Your Vehicle

Understanding what a catalytic converter is, and what it does within your exhaust system, is important for you to distinguish the best options when having to choose the difference between a direct fit and a universal fit for your vehicle. The propose of a catalytic converter is crucial for converting harmfully toxic gases, which are produced during the combustion of gasoline and diesel fuel, into carbon dioxide and water vapors, and to reduce nitrogen oxides. In this way, harmful gases such as hydrocarbons and carbon monoxide are meant to be rendered harmless, if the exhaust system if functioning properly.

Can an inefficient exhaust system hinder the ability of modern catalytic converter to reduce nitrogen oxides, and to convert harmful exhaust gases into water vapor and carbon dioxide? The answer is yes. In fact, the difference between a direct fit and a universal fit for your vehicle can improve the effectiveness of the catalytic converter. And, at the same time increase your engine’s overall performance. Here’s how.

To ensure that you’re current catalytic converter is operating at peak performance, or you are considering installing a new one and want to get the most effective use out of it, then you should know the difference between a direct fit and a universal fit for your vehicle. Below you will find a description and an explanation distinguishing the differences between a direct fit and a universal fit. But first, you need to understand the basics of how an exhaust system works.

Universal fit and direct fit catalytic converters are much like comparing a custom exhaust system to a generic exhaust system. Professional exhaust fabricators Melbourne have the knowledge and the ability to custom design an exhaust system for almost any type of vehicle. The purpose is to decrease engine noise, increase vehicle performance or to meet ever growing governmental standards. The purpose of generic exhaust system components is to reduce noise; they are not designed to increase engine performance. Understanding this will help you to know the difference between a direct fit and a universal fit for your vehicle.

Universal Fit Catalytic Converter – As the name implies, a universal fit means that a catalytic converter is generically designed to fit various engine models of cars, truck, vans and station wagons. The pros and cons of a universal fit may not be obvious to the untrained mechanic or exhaust fabricator. Most vehicle owners don’t even know what a catalytic converter does, let alone the benefits and negative effects they can have on engine performance. So, what are the pros and cons? The pros are easily understood when considering price and availability.

Universal catalytic converters are usually less costly than direct fit ones, however, the cons are observed in reduced engine performance. Why is that? Custom exhaust system components are specially fabricated using specific length and pipe widths, to take advantage of the vacuum that hot gases produce when they leave the exhaust manifold. Universal fit catalytic converters can hinder the effectiveness of a custom exhaust system, thus affecting their efficiency as well.

Direct Fit Catalytic Converters – These are specially design to fit your model of car. Direct fit catalytic converters are the ideal choice if you want to get the most out of your engines performance. Locating a Melbourne exhaust centre, one that specializes in fabricating custom exhaust components is important, if you want to install a direct fit catalytic converter into your vehicle to improve engine performance.

How To Temporarily Fix A Hole In An Exhaust Pipe?

With regards to vehicle parts, the most commonly and most easily damaged part tends to be the exhaust pipe, which more often than not breaks down due to constant heat or due to rust and weathering. Thankfully, most exhaust pipes are tough enough that the most amount of damage they get are holes. Holes tend to be of varied sizes, or one ridiculously large hole near the engine block, in the mid-section or at the furthest end of the tailpipe.

While for some folks this may curtail a much needed and immediate replacement of the exhaust pipe, there are ways to temporarily fix holes in exhaust pipes which do not necessitate costly replacement. In fact, some exhaust pipe repairs can be done right in the comfort of your own garage, and can even be a nice do-it-yourself project for the weekend until you can afford to take your vehicle into an exhaust centre. The steps on how to temporarily fix a hole in an exhaust pipe are quite simple and can be undertaken by even the most inexperienced DIY mechanic or repair-person.

Of course, there are certain things that you will need to go about repairing your exhaust pipe on your own, and this will serve as a quick guide on how to go about it.

A Quick Guide On How To Temporarily Fix A Hole In Your Exhaust Pipe

Fixing your exhaust pipe in the comfort of your own garage can be done, although there are some tools, tricks, and safety precautions that you should keep in mind. First of all, it is prudent to begin your repairs when the exhaust pipes and underbelly of the vehicle has sufficiently cooled down. While you may be tempted to work with your car in a truly ‘cold’ state, it is more advisable to try and apply either muffler repair tape or muffler repair putty while the exhaust pipe is still little warm. Why is that?

This allows for easier bonding of the material to the exhaust pipe’s ‘base’ material. Most of these easy DIY epoxy fixes for exhaust pipes often require some degree of heat to fully bond with the pipe material in need of repair. Although these types of epoxies are, in and of themselves easily workable, it is often advised to actually start your vehicle and heat it up for maximum bonding. Of course, basic rules of thumb necessitate that you clean the surface of your exhaust pipe thoroughly before attempting to repair any holes.

With respect to very large holes, using something as simple as a steel wire mesh that can cover the hole about 2 inches all around it, and then tacking it in place with exhaust repair epoxy is the first step. Then, once the epoxy has fully dried, you can then liberally wrap the pipe with exhaust tape to cover the steel wire mesh. Temporarily repairing a muffler in this way is not for everyone, and that’s ok. A professional exhaust centre Melbourne can easily repair your muffler for you, permanently, so you don’t have too.

Understanding The Basics Of How Motorcycle Exhausts Work

A large number of motorcycle enthusiasts these days are do-it-yourselfers and are very knowledgeable about the functioning of their motorcycles. Of course, this skill develops with the hobby, and later on becomes a passion that is necessary to truly immerse yourself in the motorcycle world, to get the most out of it. Still, a sizeable number of newbies to the motorcycle world need some type of introduction into the workings of motorbikes, especially over topics that go beyond the basics of maintenance and general care.

Issues like the basics of brake calibration and understanding how motorcycle exhausts work are sometimes left undiscussed, unless one takes a crash course in mechanical engineering or automotive repair. However, there’s an easy way to go about understanding how motorcycle exhausts work. Aside from watching various videos online that attempt to simplify the process, here is a brief article on what you need to know in order to understand the ins and outs of motorcycle exhausts that could help you some day.

Motorcycle Exhausts – Their Types And Functions

What is a motorcycle exhaust? A motorcycle exhaust is a complex device generally composed of piping, attached to a motorcycle’s engine. Sometimes these are chrome-plated for aesthetic reasons. However, exhaust systems can also be made from aluminum, steel, alloy, carbon fibre, and even titanium.

What does a motorcycle exhaust system do? Motorcycle exhausts mounted on the engine help to re-route noxious gases away from the rider and passenger while simultaneously muffling noise and improving engine performance. Actually, a well-maintained exhaust system can vastly improve overall engine performance and prolongs the engine’s life.

What kind of exhaust systems are there? There are basically two main kinds of exhaust systems available in the market today; a mufflers-only exhaust (properly referred to as bolt-on or slip-on system), and a full exhaust system. The latter one tends to have the added feature of being customizable or otherwise custom-made to suit different specifications and needs.

A third variety is the default exhaust systems that an average motorbike bike is equipped with upon purchasing, which some hard-core enthusiasts consider to be mediocre at best when compared to custom-made exhaust systems.

If you’re looking for a great place to find excellent examples of exhaust systems for your motorcycle, or if you’re ever in need of a high performance customised exhaust system that is sure to rev-up your bike’s speed and overall performance, then visit Trufit Exhaust today: https://www.trufitexhaust.com.au/

What is a Diesel Catalytic Converter?- Everything You Need To Know

A must-have accessory for your precious vehicles, a catalytic converter is primarily defined as an exhaust emission control device. That means, it is responsible for the reduction of toxic gases and fumes emitting from your vehicle’s internal combustion engine. With the rampant increase in pollution levels, Govt. all across the world have taken a stricter stand towards environment pollution; most of it occurring due to the frequent use of automobiles. In fact, vehicle emission was posing such a threat to our environment that the Australian Govt. in 1986 ordered vehicle owners to thoroughly clean their car emission systems for residual toxicity. This was enforced alongside a new law that made catalytic converters a mandate for every vehicle plying on the road.

Now think about your vehicle and its wellbeing. Toxic gases and fumes trapped inside your vehicle is not just a threat to the environment, but to your car too. Imagine all the toxic gases piling up inside your engine. Most of them are paving their way to more irreparable damage within.

To simplify it down, catalytic converters are responsible for converting toxic gas into less-toxic, environmentally-sustainable gas (before the vehicle emits it out of its system). And this is done through chemical reactions that strips the gases of its toxicity, thereby cleaning the gases of its harmful properties.

Catalytic Converter Exhaust- How Do They Work?

Your vehicle’s engine usually emits harmful substances in the form of nitric oxide, carbon monoxide, nitrogen dioxide etc. The sole purpose of your catalytic converter is to filter out these very harmful toxicities in the gas, leaving only carbon dioxide and water vapour as vehicle emissions. Now, the conversion is usually done through chemical reactions thanks to the catalyst present in the converter.

Your catalytic converter resembles a honeycomb structure, coated in catalysts. The honeycomb structure ensures the gas touches a broader area of catalysts. That way, the gas emitted by your engine can convert quicker and better before releasing itself from the exhaust. Usually, expensive metals such as platinum or rhodium are used as catalysts which increase the catalyst converter cost or value. Unfortunately, these catalysts are quite indispensable in nature. And because of your catalytic converters price, these accessories often fall prey to petty thefts.

Where Will I Find the Catalytic Converter in My Car?

Initially, these converters were placed near the engine, since the reactive elements in the catalyst needed high temperature to work well. However, the placement was later changed due to certain reactions. The converter was moved further away from the engine area and today you can find your catalytic converter exhaust near your vehicle’s exhaust system.

Can Catalytic Converters be Cleaned?

Your Catalytic Converters faces a lot of toxic gases which is why clogs can be a normal affair. However, ignoring a clogged catalytic converter may make your vehicle fail the emission test. This is because clogged or unclean converters reduce the efficiency of the converter. Now, your catalytic converters have a lot of noble metals in them which is why cleaning a converter can’t be a DIY project for you. Most vehicle owners trust their neighbourhood catalytic converter cleaners to get the job done. These experts do a terrific job in cleaning. What’s more? They can also ensure your converter will be in pristine condition without damage once they are done.

In fact, these converters are frequently exposed to harmful gases. Inefficiency and malfunctions are not uncommon in cases like this. Instead of splurging on a new unit, you can always opt for catalytic converter repair services from exhaust experts in Australia. In fact, if you’re working with a reputed catalytic converter cleaner in Melbourne, you can even get other services like repair or catalytic converter replacement services and not just cleaning.

Do Catalytic Converter Cleaners Really Work?

Harmful gases emitted by your vehicle has to pass through the converter. Hence, if your exhausts complain about a lot of carbon build-up, you better believe them. Carbon build-up or clogging is quite common in catalytic converters; especially if they are old. That’s why catalytic converter cleaners often focus on breaking down the stubborn build-up. So, if you’re asking whether catalytic converter cleaners work, we’d say YES! They are effective every time in clearing out the carbon build-up.

But do note, if you’re ignoring catalytic converter maintenance for way too long, chances are that your catalytic converter replacement costs will be quite high!

Is Your Catalytic Converter ‘Bad’?

In a nutshell, catalytic converters are critical for your vehicle and the environment but inadequate care or maintenance can take a toll on your converters. With years of usage, the catalytic converter’s efficiency starts declining. Before you know it, there are strange odours in your car. Your check engine light is blinking away. Your vehicle is failing all the emission tests! Now at a time like this, mere cleaning will not be enough to get your car back on the road! You may have to opt for a catalytic converter replacement.

Let us list down some of the most common symptoms that indicate a bad catalytic converter. These would include-

A rotten/ sulfur smell inside the car

Difficulty in starting your engine

The check engine light will be blinking constantly

Exhaust smoke will be darker in colour

Engine performance will degrade over time

Your vehicle will produce excessive heat

Acceleration performance will be reduced

These are just some of the basic symptoms that you may experience. The underlying damage will be much detrimental. So, what can you do at a time like this? Bring your vehicle to one of the seasoned exhaust experts in Melbourne and get a comprehensive inspection and maintenance check done on your converters.

What are Pacemaker Headers?

If you’re wondering about Pacemaker Headers, don’t attempt to puzzle out this term by yourself. You’ll end up visualising an electronic gizmo that’s intended for an ailing heart, and you’d definitely be on the wrong track. This is a brand name, a car enthusiast vendor that manufactures exhaust system headers. Australian built, Pacemaker pipework is built for performance, thanks to a pipe-over-cone feature that edges out the competition.

A Header Refresher

As you probably recall, engine headers bolt on to the exhaust manifold in your vehicle’s engine. The object of the uniquely profiled back pressure reducers is to give each cylinder its own discharge path, with the channels then blending into a single thick bore tube. When you install a header system, you’re taking the load off the cylinders by endowing them with their own outlet channel, one that then combines attractively with its peers to quickly dismiss all exhaust gases. In appearance, the pipes make your vehicle look like a muscle car, but the performance modification can go even further, just as long as you’re willing to select a top-branded manufacturer.

Pacemaker Headers: Redefining Cylinder Separation Technology

Quality exhaust headers, courtesy of Pacemaker, take this byproduct separation principle to a whole other level. First of all, the mandrel-bent pipes are specifically designed to accelerate the ejection process, so the discrete fume streams rocket out of the pipework before the exhaust back pressure even begins to hamstring engine performance. Next, an innovative engineering company enjoys leading the field, not playing follow the leader, so the Pacemaker team have been busy. They’ve added that mandrel-bent profile to the mix, then brought their engineering acumen deeper into the architecture of the headers to deal a blow to the turbulence that develops when these discrete byproduct streams recombine. The solution is Pipe Over Cone technology, a header profile feature that significantly reduces gaseous turbulence so that the gases move unhindered towards the exhaust tips.

A peek inside the vendor-tuned pipes shows a design that doesn’t place a protruding pipe inside the collector cone. Instead, Pacemaker Headers focus on singular innovative solutions, products that curve while never attenuating the exhaust stream as it travels away from the engine manifold. Add to that the copyrighted pipe over cone feature, a design that draws upon the laws of fluid dynamics, and this product family easily gives any other header vendor a run for its money. Built to inject your next bolt on set of headers with added performance, Pacemaker Headers are also long lasting, designed to fit many popular cars, and a product of a dedicated R&D environment.

What are Selective Catalytic Reduction and Urea Injection?

Injection systems improve engine performance, so why shouldn’t a similar mechanism enhance your exhaust output? Instead of fuel injection, however, the tech we’re about to discuss injects Urea into diesel exhaust streams. Buckle in while we explain what’s known as Selective Catalytic Reduction and Urea injection. It’s a chemical process that’s been used in industrial diesel engines for some time now, and it’s also found in car exhaust systems.

What is Selective Catalytic Reduction (SCR)?

Selective catalytic reduction technology uses an active chemical injectant as an emission mitigation solution. Specifically, the catalytic agent targets the poisonous nitrogen oxide (Nox) fumes in your exhaust, which is why the technology earns the “selective” prefix. Down among the exhaust pipes, a dosing tank is injecting a gaseous reductant into the engine byproduct stream. A redox reaction takes place between the reductant and the nitrogen oxide. Basically, through some invisible chemical process, the noxious gases are transformed into harmless nitrogen and water, elements that can’t harm the environment.

What about the Urea?

Chemists refer to Urea by its technical label, so substitute that short word with a longer chemical name, something chemical engineers call Aqueous Ammonia. That active liquid compound is what’s injected into the exhaust stream, but we less science-centric types simply call the chemical Urea. Anyway, call it Urea or Aqueous Ammonia, it doesn’t really matter. What does matter is what happens when this chemical and the Nox pass through a catalysing agent. Typically formed from ceramic and some exotic metal (Titanium Oxide or Vanadium Oxide), the honeycombed catalyst converts the Nitrogen Oxide into harmless hydrogen dioxide and nitrogen, plus a few trace wisps of Carbon Dioxide (Co2).

Bringing It All Together

You don’t need a chemistry degree to see how this active emission management system operates. The dosing unit passes NH3 (Ammonia) into the catalyst chamber. Those perforated plates, the Titanium Oxide honeycomb, then swaps electrons and elements so that new compounds form. Now, as stated right in our initial passage, the Selective Catalytic Reduction process has been operating in industrial engines for some time, but the system can scale, so performance cars are enjoying emission attenuation figures that hover around the ninety-percent mark. That Nox reduction figure creates a compelling reason to consider SCR technology.

Passive exhaust system solutions work well when stock factory exhaust systems roll off the assembly line. For a performance engine, though, an active emissions management system represents a welcome addition to the performance exhaust system family, one that uses dosing Urea and a special catalyst to really inhibit the Nox gases.

Definition and Functions of Lake Pipes

Car mods are designed to augment engine performance. Of course, an aesthetic enhancement is also desirable, but engine improvements come first. Lake pipes adhere to this core aftermarket principle by first enhancing engine respiration, but they also follow the second law of the aftermarket charter. That’s right, they inject cars with retro appeal. Stylish by design, what does it take to create this iconic 1950s exhaust mod?

Exposed Piping

When a gearhead allows his four-wheeled addiction to take over, a car’s suspension sometimes drops. The lowered body profile looks cool, but the chassis is now scraping the road. Imagine performance enthusiasts debating what to do with the exhaust pipes when they’re faced with this issue. They pause for a moment, sure, but then the work surges forward again as the pipes move up and out to the side of the chassis. This move preceded the birth of the first lake pipes. Side-mounted and fully exposed, the long tubes hugged the lower sides of the vehicle while emphasizing a rocket-like style.

The Evolved Hot Rod

The developing lake exhaust market was all about 1950s style, a retro look that, while evoking images of comic-book rocket engines, didn’t really add much in the way of a performance gain. Newer products look just as amazing as the original pipework, just as capable of evoking that powerful mid-twentieth century coolness factor, but they add real world performance. Top-notch pipe bends accommodate back-pressure release requirements. Premium alloys are fabricated as wide diameter tubes, bifurcating channels that bolt in place of waste constraining exhaust manifolds. In short, yesteryears side-mounted style still rocks, but that look now sports contemporary performance features.

Brings Retro Credentials

There was a reason these long pipes adorned lake cars. The modification was designed to make the engine roar with unmuted power, but noise wasn’t an issue because the chrome-coated tubes were blasting gas while racing along dry lake beds. As such, basic flapper valves and dump conduits were once used to keep things toned down when the car was rumbling through populated areas. Modern lake pipes are arguably still best suited for remote raceways, but new designs do dramatically cut the aggressive growl.

Built originally to allow vehicle suspensions to drop precipitously, exposed exhaust systems decorated hot rod side panels for decades while drivers raced in dust bowls and dry lake beds. Today, the retro pipework is coming out of the shadows as a way of showing off beautifully worked pipe layouts, systems that make performance addicts salivate with nostalgia-induced envy.

Functions of Oxygen Sensors in Exhaust Systems

Back in the day, the earliest exhaust systems were dumb metal linkages. Sure, the welded pipes worked efficiently. They rid the engine of waste gasses well enough, but there was no emissions control in the system. Today’s exhaust pipes are smart by design. They incorporate a special oxygen monitor, an O2 sensor that monitors and controls engine emissions. It’s all about feedback, but what is this control loop altering?

Fuel Mixture

Oxygen sensors (O2) are typically installed in the exhaust manifold. They monitor oxygen because this is the atmospheric gas that mixes with your fuel to generate combustion. Engines are finely tuned so that the bulk of the fuel is burnt and no waste remains, but if the burn ratio is oxygen rich, well, this heavy mix will induce waste. Similarly, a lean oxygen-to-fuel mix also produces pollution. The O2 sensors detect this misbalance and send the data to your engine’s computer, which is when the check engine light starts to flash its warning.

Active Emission Control 

If the fuel/oxygen ratio is out of whack, pollution is produced, but the onboard sensors are always on hand to inform you of this environmental hazard. Technology doesn’t stop there, though, not when the feedback loop is buzzing away to constantly update the burn ratio. The engine computer regulates the mixture, takes its cue from the tiny feedback loop so that it can manage the amount of oxygen entering the combustion cycle.

Safety in Numbers

As emission control standards tighten, the number of oxygen detectors installed in modern vehicles has doubled. For example, there’s an input detector mounted in front of the catalytic converter. It sniffs the input mix while a second downstream monitor takes note of the output oxygen-to-fuel blend. The computer does a little arithmetic, compares the two values, and gives the cat unit an invisible check mark. Both the engine exhaust manifold and the rest of the exhaust system deliver constantly monitored output signals in this manner, all so that the closed feedback loop will keep the burn cycle perfectly balanced.

On the surfaces, O2 sensors seem designed to burn out Engine Check lights and cause you headaches, but their true purpose is to inform your vehicle’s computer, to precisely monitor the fuel/ oxygen mix. If that explosive blend is just so, well, no pollutants are generated, but if it burns too rich or too lean, hazardous emissions will flow. Worse still, your fuel economy will suffer while engine performance drops and key components incur damage.

Pros and Cons to Consider Before Customising Your Motorcycle Exhaust System

Few aftermarket projects yield results that can compare to the addition of a customised motorcycle exhaust system. Sure, the best car pipes deliver impressive performance gains, but the gains are rarely as viscerally good looking as the mods found on motorbikes. Still, not all bike exhaust mods deliver the goods. Let’s see why.

Avoiding Chassis Half Measures

Motorcycles don’t need to be raised on a hydraulic platform. Accessibility isn’t an issue, then, but there’s just not as much real estate available when the time comes to bolt on the new aftermarket motorcycle exhaust system. We think that fact represents an installation drawback.

Visually Engaging Profile

The notion that an attractive double-barreled pipe makes heads turn seems like a benefit, but, performance-wise, the good looks suggest the design is coming up short. Basically, some manufacturers see the exposed pipes as an opportunity to show off polished chrome while ignoring the chance to boost engine breathing.

Motorcycle Legislative Mandates

This next discussion is going to vary according to the owner’s nationality. Objectively, many nations use different noise regulations, rules that separate contrasting vehicle types. Motorcycles, for instance, are classed as Category LC and LD vehicles, so, according to this Standardization Act (Australia), there’s a little more leeway available in the two-wheeled exhaust system market. Keep that ruling in mind as a definite pro when adding raw noise and volume to the pipes, at least until the legislature is changed.

Slip-On VS. Full System Replacement

Simple slip-ons reduce the weight of the bike and slightly improve exhaust breathability. The factory muffler tips are gone, with the new tips changing the acoustic profile of the engine, but that’s about all the performance enhancements that you can expect. A full system substitution removes the pipework all the way back to the engine headers. A performance boost is assured, but the installation typically requires a knowledgeable garage, for fuel intake alterations and engine tuning is recommended after such a major system alteration.

Weight reductions are another gain to expect, especially since the motorcycle exhaust system occupies a significant part of the two-wheelers load ratio. Opt for that full system replacement by buying-in a titanium or carbon fiber casing, but do remember that the handling characteristics will alter after the modification has been completed. Otherwise, bear in mind the fact that a svelte new pipe rack doesn’t always equal significant engine enhancements. Make those aftermarket changes at a garage, a place that expertly matches good looks to augmented engine breathing.

Tips for Choosing the Right Exhaust System that will Match Your Engine Capacity

Exhaust system modifications produce readily accessible engine efficiency gains. In essence, wide diameter pipes and bolt-on kits act as a gateway to increased performance. One moment, though, these alterations only work properly if the car’s engine capacity is matched with the right exhaust system. Otherwise, you reach a point of diminishing returns where performance gains flat line. Here are some handy tips for avoiding this horsepower plateau.

Squeeze the Engine for Extra Horsepower

If the exhaust system is open to modification, then so is the engine. Properly establish the engine’s capabilities before turning your attention to the exhaust system. Turbochargers and customized cold-air intake mods involve extra parts, so keep that added expense in mind. If that added expenditure doesn’t ring your bell, then pull the vehicle into your local garage for a full computer tune-up. Basically, push the engine’s power train to its limits before going to work on the breathing channels.

What about Engine Capacity?

There’s a capacity number stamped on the engine or emblazoned on the car paneling. When you encounter it, you store it away in the back of your mind, but maybe you never give it any further consideration. It becomes one of those stored little facts that float to the surface of your mind every so often. That’s fine, except you’ll need to know a bit more if you seriously intend matching a new exhaust system to your engine.

A Dictionary-type Definition

Engine capacity, also known as sweep volume or engine displacement, refers to the amount of space swept by the pistons inside their cylinder casings. Measured in liters, bigger numbers equal more space for the fuel and air to mix. As a general rule of thumb, more power is generated when this value is larger.

Balanced RPM Management

Ideally, the potential exhaust system replacement kit would match the generated torque and the capacity of the engine across all RPM bands by switching bores, but multiple sets of pipes aren’t exactly practical. Instead, a balance is struck by selecting a bore that complements this capacity rating. Enthusiast versions target a more exaggerated performance profile, though, a higher RPM band that delivers aggressive torque characteristics.

Understand the engine’s characteristics and the full meaning of the engine capacity rating. Next, associate this key knowledge with mods that improve the torque of the engine at the source. Finally, research branded exhaust systems so that their aggressive performance characteristics can be matched to the capacity of the engine.
