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.

What Are Exhaust Manifolds?

Exhaust manifolds are designed to couple each exhaust port of an engine’s cylinder head to a single outlet pipe. Functionally, the steely unit collects ejected waste gasses from the multiple cylinders and ejects them into a single pipe conduit. Viewed from a purely structural viewpoint, the little collector unit is manufactured as a blocky series of aligned ports. Its job is to merge the collected streams of cylinder-burnt gasses, to combine the multiple exhaust outlets into a single channel. Let’s take a closer look.

Engine-to-Exhaust System Interface

Exhaust manifolds bolt to car engines via heat-resistant gaskets. They’re the compact factory-installed workhorses that convert multiple exhaust outputs into a lone stream so that the unified volume of dirty gas can be expelled down one channel and out through a car’s tailpipe. Unfortunately, that compact profile does not favour free engine respiration. It’s a bit like dropping your head to your chest and trying to breathe freely. It just doesn’t work well, and you end up feeling breathless. An aftermarket exhaust manifold opens up output next to the point that it’s generated. As a result, that hypothetical neck is now stretching to maximize volumetric flow.

Examining the Structural Configuration

This is a critical juncture because it’s the first turn and mixing chamber encountered by the pressurized emissions after they leave the confines of the engine. Consequently, a structure that causes volumetric constriction will decrease the efficiency of the system. Certainly, the multiple output ports are properly sealed by the gasket. Their diameter is broad and the manifold chamber is fairly spacious, but the internal space defined by the contours of the manifold junction are still far from ideal. Again, back pressure problems will manifest when this engine fixture is spatially constrictive.

Accounting for Material Shortcomings

The cast iron or fabricated steel housing is capable of absorbing copious amounts of heat, but that same material will become brittle as it ages. Likewise, the coarse microcrystalline structure used by the sourced metal creates a subtle drag factor, so exhaust ejection ratios are further attenuated. In simple terms, the exhaust collecting aptitude of the product is not in question, but it’s structural and material build does place a big question mark over the collector’s backpressure minimizing capabilities.

An nth amount in and one out exhaust manifold configuration works expeditiously, but geometry improvements and material subsidization will enhance this critical juncture point. Better yet, consider looking into a header replacement if you’re really passionate about horsepower scavenging.

Functional Differences between Mufflers and Exhaust Systems

It’s not always easy to discern the differences between mufflers and exhaust systems. That’s probably because some of us are guilty of liberally swapping the terms whenever it suits us, but this practice needs to stop. End that confusion by remembering a muffler is a chamber for “muffling” the noise generated by the exhaust system. Then, drive that point home by knowing the full architecture of a top-of-the-line exhaust system.

What is A Muffler?

This chamber lives as an inline component within the exhaust system. It’s generally located at the end of the pipes, just before the tailpipe. Now, there might be a tailpipe extension down there, perhaps a couple of mechanical clamps supporting the additional pipe section, but this noise attenuator is still located at the rear end of the piping. It’s generally filled with chambers and perforated tubes. Functionally, this little devil should absorb sounds so that the car runs quietly. Realistically, at least on performance vehicles, the pressure waves generated by the fast-moving gases are aggressively tuned by aftermarket mufflers so that they create a throaty roar.

Functional Differences

Aftermarket exhaust systems are designed to enhance cars by intelligently shaping certain performance curves. They improve engine breathing by widening the bores of the pipes, then assume a profile that accelerates the gas stream towards the tailpipe. Emission control takes place here as well, with O2 sensors and a catalytic converter taking charge of this environmentally responsible effort. Conversely, the muffler breaks away from this straight-line solution by adopting a bouncing mode of operation. There’s a resonation chamber in here, plus baffles and perforated tubes. Alternatively, straight-through mufflers dismiss the chambers, and their maximum flow characteristics do favour the engine, but these beasts deliver ear-splitting noise.

Resonator or Muffler: Is There A Difference?

The short answer is yes, their two chambers are not the same. A muffler, as covered earlier, is built to silence noise. Performance variants on this theme have introduced a resonator chamber inside the muffler, but this apparatus is still very much a sound attenuator. A purebred resonator targets certain sound frequencies and pulsed pressure waves. Essentially, if the car is mixing a high-frequency saw-like tone with its animalistic roar, the resonator will cancel out the higher tones, which then leaves behind pure animal.

Balance is a must here, so a quality-assured garage needs to get in on the act. The garage looks at chambered mufflers and straight-through solutions. The engineer balances the breathe-easy nature of the glass-pack with the quieter but pressure hampering qualities of the chambered muffler, all so that the inline unit functions as a hard-working member of the exhaust system’s pipes and boxes.

Diesel versus Gas Engine: Is There Any Difference on How an Exhaust System Works with Each Fuel Type

The diesel versus gas engine debate has been around forever. Both fuel sources require different types of engines because their fuel sources expend energy via two opposing methods. Meanwhile, turbochargers and fuel injection systems add complexity to the mechanical innards in the diesel compartment. These design factors explain engine performance differences and the need to roll up to the right pumps, but how do they affect exhaust system differences? In point of fact, are there any differences between them?

Compression Contrary Designs

Engine Compression characteristics are pushed to the limit in diesel applications. Temperatures rise higher, internal pressures are elevated, and gas velocities are accelerated. Conversely, more torque is generated by a diesel engine than a comparable gas model, so these lower RPMs will produce as much power as a fast-cycling gas engine.

Supplemented With Turbocharger Kits

The spark-less cylinders in a diesel engine rely on a compression ignition cycle, so a wide-bore exhaust system is required to handle the ignition pressure. Modern diesel vehicles also add a turbocharger, an engine augmentation solution that enhances overall power output. Turbocharger technology pre-compresses the air so that the fuel-air mix is enriched. Again, pressure and volumetric capacity parameters highlight a significant difference, so diesel exhaust systems do tend to assume a wide diameter profile.

Diesel Exhaust Systems

Modern diesel cars throw out more noxious fumes than a petrol-based (gasoline-fueled) car. The diesel exhaust isn’t as physically corrosive as the junk leaving a petrol engine, but it does more damage when enters the environment. In principle, a top-notch diesel system could use thinner materials in its construction because of this non-corrosive flow, but remember what we said about pressure and temperature. That’s right, the diesel tubes and chambers require armouring if they’re to handle these two internalized forces. As for the noxious output’s effects on the environment, the harmful emissions require additional sensors and smarter oxidizing solutions to remove this chemical soup.

There’s a spark plug assisting the gasoline engine. No such combustion assistance is at work in a diesel engine, which is why design balance is required in an aftermarket kit. The balance accommodates the high engine compression ratio by opening up the pipes. The other side of the solution, though, is a more active emissions control system, an asset that neutralizes diesel particulates, NOx (Nitrogen Oxide), and carbon monoxide. That catalyzing agent and the widened exhaust tubes then work efficiently so that the engine turbocharger operates at full capacity.

What is a Header Back Exhaust System?

Vehicle engineers have established broad exit channels for car engine exhaust, but there’s always room for improvement. A header back exhaust system reinforces this maxim by pulling up the proverbial bootstraps of the aftermarket craftsman and extending the factory replacement process all the way to the engine manifold. For a portrayal of how this process makes headway, read on and embrace our tailpipe-to-engine rundown.

Power-robbing exhaust components go straight out the window when the kit extends all the way to the engine header. Everything, and we mean everything, is swapped out during this expansive upgrade. In doing so, the diameter of the exhaust pipework is increased, as is any intermediate linkages and crossover pipes. Finally, the muffler and catalytic converter can optionally be ousted in favour of improved chambers, but this latter rationale is subject to a manufacturer’s interpretation of the kit.

Removing System Bottlenecks

A comprehensive solution like this is the only way to truly ensure uninhibited performance, for every part of the engine cleansing pipework, every emission cleansing component, and every noise abating chamber is removed from the vehicle. Instead, there’s new potential, a metaphorical blank sheet where literally an entirely new exhaust system can be installed as a kit. Benefits in this situation include predictable backpressure reduction ratings and increased fuel economy, all because pipework-related bottlenecks are gone. Likewise, the raw sound envelope of the vehicle submits to engineer adjustments because every piece of kit is liberated from the parts-coupling hindrances associated with a partial replacement strategy.

Purchasing the Kit

When the time comes to pull out hard cash, the enthusiast motorist knows what to expect, but the provided parts can daze beginners. Typically, all the pipes and clamps for the pipes are supplied. There will be a number of bends on the metal channels, so a fully customized exhaust configuration is entirely possible. All bolt-on assemblies come as part of the exhaust kit, but there’s a possibility that both the muffler and catalytic converter could be excluded, so bear this fact in mind when engaging in this major upgrade.

Buy this engine-to-tailpipe kit when seeking a generous increase in vehicle power. Likewise, buy this kit when freedom of choice means everything, for different header back exhaust systems enable various tailpipe configurations and engine manifold kits to be employed during the upgrade process. Finally, these restructuring techniques eliminate system bottlenecks, thus improving fuel economy and the gruff tones of the muffler.
