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.

The Mad Catted N55 Downpipe is also equipped with high-flow catalytic converters, which help to reduce harmful emissions while maintaining optimal performance levels. The catalytic converters are engineered to deliver maximum flow and minimal back pressure, which results in a noticeable improvement in engine sound and overall driving experience.    

The downpipe is designed to bolt-on directly to the stock exhaust system and does not require any cutting or welding, making installation quick and hassle-free. The Mad Catted N55 Downpipe is also compatible with aftermarket exhaust systems, providing you with endless customization options to suit your preferences.

Don't settle for stock performance - upgrade to the Mad N55 200 Cell Race Catted Downpipes and experience the true potential of your BMW.

Metric Hardware
Size: 89-96158T 1PC
Works fine. This has metric hardware, which does not match the other two relays on my vintage mercury outboard. This is not a quicksilver part
