Introducing the Mad Catted N55 Downpipe, the perfect upgrade for BMW enthusiasts looking to enhance their vehicle’s performance and exhaust sound.

Crafted from premium quality 304 stainless steel, this downpipe is built to withstand extreme temperatures and harsh driving conditions. The smooth transition of our piping design ensures maximum exhaust flow, which results in increased horsepower, torque, and throttle response.
