The Wagner decat downpipe is developed for BMW models with the N55 engine (from 07/2013) and is manufactured from high-quality stainless steel 1.4301 (SS304) with a CAD design for a perfect fit.
With a diameter of Ø76 mm The downpipe promotes gas flow and reduces back pressure in the exhaust system, resulting in faster engine response and more power and torque. The connection diameter is 118 mm. The downpipe is designed without main catalytic converter and features two lambda sensor connectionsThe 100% perfect fit makes the downpipe a simple replacement for the original part without additional modifications, and reduces the thermal load on the turbo. The downpipe is suitable for the M135i (F20/F21), M235i (F22), M2 (F87, not the Competition version), 335i (F30/F31/F34) and 435i (F32/F33) from July 2013.
