Put in the simplest possible terms, a performance exhaust system replaces some or all your car's original exhaust system with improved pipework, silencers, and the like.
It will also have been designed for the original power output of the engine. It's probably perfectly adequate for that power level, but once you start tuning the car it can become a limitation.
This means there are two big areas for improvement for performance exhaust makers – sound and performance. If you are also looking for the best exhaust system then you can shop for Black OPS high-performance exhaust system online.
The sound is one of the biggest pull factors for some owners. A performance exhaust can transform the sound of a car. The combination of pipework and silencers means each manufacturer can achieve their own trademark sound.
While you probably notice the very loud aftermarket exhausts more, there's actually a whole range of sounds on offer, depending on who's exhaust you are fitting to your car.
This can range from the very boisterous through to a refined performance car sound. Most manufacturers will have a consistent quality to their sound.
A better flowing exhaust can help your car to generate more BHP. How quickly you can get the exhaust gasses out of the engine places a limit on how quickly you can get fresh air into the engine and thus how much power can be made.
A better flowing exhaust always improves the power your engine can make. Performance exhausts achieve this in several ways. Pipework diameter, exhaust layout, and reducing obstructions in the exhaust all play their part.
The quicker everything is flowing, the more benefit you get from this. On a turbo-car, the big priority is increasing the flow rate of the exhaust. The more gas the turbo can get out, the more efficiently it can force-feed your engine with air at the other end.
