Catted vs Catless B58 Downpipes

We provide two types of B58 downpipes: catted and catless. Our customers have different needs and preferences, so we offer both options. When installed on a stock B58 car, the high flow catted downpipe offers a performance boost, while the catless downpipe can provide an additional 15-20 horsepower increase.
