The Wagner Downpipe kit is specially designed for the BMW M140i with B58 engine and is available with or without a racing catalytic converter, depending on your preferences. The downpipe is manufactured from high-quality cast stainless steel, which ensures excellent durability and corrosion resistance and withstands the high temperatures and pressure generated during driving.
With a diameter of Ø3.5 inch Featuring a smart adapter for a perfect fit on the original exhaust system, this downpipe is easy to install. The CAD designs ensure optimal flow. With two lambda sensor connections, accurate exhaust gas measurements can be performed, contributing to better engine tuning and efficiency. Replacing the standard downpipe reduces the thermal load on the turbo, extending the turbo's lifespan. Furthermore, the kit can deliver a noticeable increase in torque and power.
