Which exhaust has the best sound?
Cat-back exhausts These are full exhaust systems from the catalytic converter to the exhaust pipe at the back of the car. As well as the muffler and tail pipe, you’ll also get the mid and intermediate pipes. These are the best sounding exhausts that will also give you some power gains. Does straight pipe affect the engine? Straight piping can affect engine performance by reducing backpressure, which might lower low-end power. However, it can enhance high-end performance in some cases.Increased Performance: Any free-flowing exhaust system increases horsepower, although somewhat, unless backed by complimentary modifications. A straight pipe exhaust with minimum backpressure can increase an engine’s power output, especially at the top end.
