The time and money you spend are a big investment, and we want to help you make the best decision for your driving dreams. Typically, a cat-back exhaust system will increase your car’s horsepower by somewhere between 5 and 50 brake horsepower. This will vary greatly depending on the condition of your exhaust and engine, so you should ask your mechanic if getting a cat-back exhaust is the best way to improve the performance of your car.

Cat-back exhaust systems replace all the components after the catalytic converter, sometimes referred to as the cat. Now you can upgrade your downpipe or mid-pipe depending on your applications. Some cat-back systems will include a mid-pipe depending on your cat layout. And when you want to make more power and take your vehicle to the next level, then you will be ready for an exhaust manifold. Available only from Mallett Performance Cars, this exhaust system is made from 304 stainless steel and features the highest quality mufflers and resonators.
