Introducing the MAD S58 Catted Downpipes
The perfect upgrade for BMW X3M and X4M owners looking to unlock more performance and a deeper, more aggressive exhaust note without triggering a check engine light.
Crafted from high-quality 304 stainless steel, these downpipes are built to withstand extreme heat and demanding driving conditions. The smooth mandrel-bent design maximizes exhaust flow, resulting in noticeable gains in horsepower, torque, and throttle response.
Equipped with 300 cell high-flow catalytic converters, the MAD S58 Catted Downpipes enhance exhaust sound and overall drivability while keeping the check engine light off. They bolt directly to the factory exhaust system with no cutting or welding required, making installation straightforward and hassle-free. They are also fully compatible with most aftermarket exhaust systems, allowing you to build the setup that best suits your goals.
No CEL Guarantee
If you receive a check engine light related to the catalytic converters, MAD will replace the downpipes free of charge.
Dont settle for stock performance. Upgrade to the MAD S58 300 Cell Race Catted Downpipes and experience the full potential of your BMW X3M or X4M.
