The most important area of cars is the engine bay, specifically the engine itself. It powers the whole car, not just its movement, but also its safety systems and convenience features such as the air con any heating elements and the infotainment system. The engine is quite a serious system since it powers every other system in your car but there's one that helps the engine work better without needing its power.

This is the exhaust system which is what gets the fumes generated by the engine. These fumes are then filtered through different components, part of the exhaust, This way your vehicle produces little noise and it also pollutes a lot less than it usually would, especially without the advancements made today.

Benefits of an Aftermarket Performance Exhaust

Acceleration

The restrictive nature of a stock exhaust is good for urban driving, but when it comes to backroad driving or on the motorway, performance exhaust systems for cars are preferred. Especially if you visit the track, finding an aftermarket exhaust online is crucial in order to improve acceleration speeds. With an aftermarket performance exhaust that's exactly what you get, quicker acceleration even from a standstill.

Top Speed

Another benefit of a performance exhaust is, as you would expect, top speed. While you won't always get near your car's top speed it's going to be higher than what's shown on the speedometer.

Response

The better your car responds when using the accelerator pedal the better it will be at making faster lap times. Faster acceleration also makes it easier to get up to motorway speed or when taking over a car.

Important Aspects of Performance Exhausts

Material

There are many different materials being used for the making of performance exhausts. You've got aluminised steel, stainless steel, titanium and Inconel. Aluminised steel exhausts are definitely a lot better than any stock solution but they aren't as strong as stainless steel exhausts which are also lighter and better at fending off corrosion.

Titanium is the lightest and strongest material a performance exhaust system can be made of while Inconel is the most advanced. This super alloy can withstand high pressure, high temperatures, and mechanical loads without a hitch. It's also the most expensive.

Drone

Although a performance exhaust should sound the same way it performs it shouldn't be droney. It may not be anything to complain about in the beginning This will become annoying even in the cabin rather quickly. But if the aftermarket exhaust online that you're after offers no escape from the droning sound, then you should consider getting drone-cancelling technology.

Diameter

The diameter of the piping affects airflow and the larger they are the better the flow of gasses will be. But that doesn't mean you should always go for larger-diameter piping. If you go for too large of a pipe diameter you can end up creating what is known as exhaust back pressure. This is definitely worse than getting smaller-diameter piping.

Valve

To valve or not to valve? That is the question to ask yourself when looking for a performance exhaust system. If you decide to go for a valved exhaust then expect to have a more versatile solution as it allows you to open up the valve and close it. Why is a valve so special? Because it lets you muffle your exhaust or make it sound as aggressive as it gets. It's up to you when and where you want to be heard or not.

Bends

The way performance exhaust systems for sale are bent will tell you a lot about how well they'll let engine fumes go by. If a performance exhaust is crush-bent then it will have wrinkles at the bends which means it has a more restrictive nature. An exhaust that's been mandrel bent will be smooth throughout. This means there'll be no restrictions.

Types of Exhausts

Header-Back

The most complete performance exhaust you'll come across, if your vehicle doesn't have a turbo, is a header-back exhaust. This type of exhaust replaces every single component and thus allows you to make your new exhaust as custom as you want. You get to decide on all of the above specs and features.

Cat-Back

If customisation isn't something you're fully going for but still want to get solid performance improvements then you should consider going for a cat-back exhaust. This type of performance exhaust isn't going to blow your mind but it will definitely introduce a different feeling when accelerating. This is because it replaces components starting from the catalytic converter to the tailpipe(s).

Turbo-Back

A turbo-back exhaust is the same as a header-back performance exhaust system except it's meant to be used on turboed vehicles. They require a bit more time and effort to be spend in order to install such an exhaust but the same customisation and freedom are present.
