Drivers wanting to take the next step in exhaust performance, Scorpion technicians have provided the solution with a sports catalyst or de-cat downpipe. Sports catalyst downpipes are fitted with a 200 cell, high-flow performance catalyst which has a much greater flow over OEM. De-cat downpipes remove the catalyst all-together resulting in unobstructed gas-flow and is perfectly engineered for those pushing the boundaries of exhaust performance. (For closed circuit use only)
