MAD S58 200 Cell Race Catted Downpipes
Designed for the BMW F97 X3M and F98 X4M, MAD S58 200 Cell Race Catted Downpipes improve exhaust flow while delivering a deeper, more aggressive exhaust note.
Increased Flow for Performance-Focused Builds
Constructed from high-quality 304 stainless steel, these downpipes are built to withstand extreme exhaust temperatures and demanding driving conditions. Smooth mandrel-bent piping and 200-cell high-flow catalytic converters reduce restriction, supporting improved horsepower, torque, and throttle response.
The freer-flowing design can provide gains of up to 30 horsepower on stock turbochargers, with additional potential on upgraded turbo setups. It also sharpens the character of the S58 exhaust without introducing excessive drone.
MAD S58 downpipes bolt directly to the factory exhaust system without cutting or welding. They are also compatible with most aftermarket exhaust systems, giving owners flexibility when planning future exhaust upgrades.
These 200-cell race catted downpipes do not include a check engine light guarantee.
