Product Description

The Wagner Tuning N55 Sports Cat Downpipe is a high-flow performance upgrade for selected BMW N55-powered F-Series models, including the F20/F21 M135i, F22 M235i, F3X 335i, F3X 435i and F87 M2 Non-Competition.

Designed as a direct replacement for the OEM BMW downpipe, this Wagner sports cat reduces exhaust back pressure to help improve turbocharger efficiency, increase power and deliver significantly stronger torque.

Manufactured from high-quality 1.4301 stainless steel / SS304, the downpipe features a 300CPSI racing catalytic converter with Euro 6 coating, offering a performance-focused alternative to the restrictive factory catalyst while retaining a catted design.

With a 105mm connection diameter, 4.0kg weight and 100% perfect-fit OEM replacement design, this downpipe is ideal for tuned N55 builds where improved exhaust flow, reduced thermal load and sharper performance are required.
