Cat Backs

For more power, better sound, and an increase in fuel economy, installing aftermarket cat backs should be one of the first upgrades you make to your 4x4 vehicle. 

Cat backs are the part of the exhaust system behind the catalytic converter, consisting of a resonator, piping and muffler.

Aftermarket cat backs produce a more pronounced exhaust tone than a stock exhaust because of their straight-through muffler design. They are constructed using mandrel bends instead of crush bends, meaning you get a better exhaust flow through the intermediate pipe. Their larger diameter piping also improves exhaust flow, resulting in more horsepower and a more aggressive performance sound. 

At PPD Performance, we sell brand new cat backs designed specifically to fit your 4x4 vehicle.
