The Wagner Downpipe 300CPSI is a Downpipe with a sports catalytic converter, specially developed for the BMW M135i and other models fitted with the N55 engine from July 2013 onwards, and improves exhaust gas flow. With a diameter of Ø76 mm, exhaust gases are efficiently discharged. The Downpipe is manufactured from high-quality 1.4301 stainless steel (SS304) for durability and corrosion resistance, and the CAD design guarantees a perfect fit, ensuring installation without the need for modifications.
The Downpipe features two lambda probe connections for flexible configurations and a racing catalytic converter with a value of 300 CPSI, featuring a high-quality Euro 6 coating for optimum performance and environmental compatibility. The Downpipe reduces the thermal load on the turbo and lowers the back pressure in the exhaust system, contributing to higher torque and power. With a connection diameter of 118 mm, installation is precise, whilst its light weight of just 4.0 kg helps to reduce overall weight. The Downpipe fits the BMW M135i(x) F20/F21 (from 07/2013), M235i(x) F22, M2 F87 N55 (not the Competition version), 335i(x) F30/F31/F34 (from July 2013), 435i(x) F32/F33 (from July 2013), X3 M35i F25 LCI (from 2014) and X4 M35i F26 / M40i (from July 2014). An error message may appear in the DME.
