The Wagner Decat downpipe kit has been developed for the BMW N55 engine and is made from stainless steel casting 1.4301 (SS304) for a long service life and maximum resistance to heat and corrosion. With a diameter of Ø76 mm The downpipe has been optimized to maximize exhaust gas flow. The CAD design ensures a perfect fit, making installation a simple replacement of the standard part.
The downpipe is supplied without a main catalytic converter, which reduces back pressure and improves vehicle performance. The absence of the main catalytic converter also reduces the thermal load on the turbo, which extends the turbo's lifespan. Thanks to two lambda sensor connections, the downpipe is compatible and flexible for various configurations. The kit fits the BMW 135i E82/E88 and the BMW 335(x)i E90/E91/E92/E93The software file must be modified to prevent the issuance of error codes in the DME.
