First and for most, cat-back exhaust generate louder & deeper exhaust tones.  How that sound produced is where the true benefit of your new upgrade lies. Cat-back systems generally have larger diameter piping.  Good systems will also have mandrel-bent turns.  Both larger diameter piping and mandrel-bent turns help reduce the level of back pressure at the engine manifold, allowing your engine to breathe better. In turn, this creates more horsepower, torque, and even gas mileage. Additionally, most systems are made from Stainless Steel, which can withstand more elements and have greater longevity.
