The Wagner Decat downpipe has been developed for the BMW M135i and takes the vehicle's performance to a new level, suitable for both street and track use. With an optimal diameter of Ø76 mm This downpipe promotes improved exhaust gas flow and optimized power delivery. The downpipe is manufactured from high-quality stainless steel 1.4301 (SS304) for long-term durability and corrosion resistance.
Thanks to CAD design technology, every detail has been carefully developed for a perfect fit and optimal performance. The downpipe is equipped with two lambda sensor connections for maximum flexibility and compatibility with various configurations. Due to the absence of the main catalytic converter, the downpipe reduces back pressure. The connection diameter is 105 mm for a suitable installation. The downpipe can be seamlessly replaced by the standard part without additional modifications (100% fit) and protects the turbocharger from excessive heat, which contributes to the lifespan of the engine. The software data state must be adjusted to prevent error codes in the DME.
