The Wagner Downpipe kit of 300CSI racing catalytic converter lifts the performance of the Audi S4 B9 and S5 F5 3.0 TFSI to a new level. The kit optimizes exhaust gas flow, resulting in a performance improvement on both the road and the track. The downpipe is manufactured from high-quality cast stainless steel 1.4301 (SS304) for exceptional durability and corrosion resistance.
Thanks to the CAD design the downpipe is optimized for maximum flow, which helps reduce back pressure and increase torque. The kit is equipped with a lambda sensor connection at the OEM position for accurate exhaust gas measurements. The Racing metal catalytic converter with 300 CSI EU6 coating ensures optimal exhaust gas purification. The kit comes with 2x Ø3" tubes and an adapter on the original exhaust, with a 100% fit for easy replacement of the standard components. The downpipe reduces the thermal load on the turbo, which contributes to its lifespan. An error message in the DME is possible.
