Wagner Tuning BMW F-Series N55 Performance Downpipe Kit -6/13

High-Flow Sports Cat Front Pipe for BMW F-Series N55 3.0T (builds to 06/2013)

Unlock smoother exhaust flow and stronger mid-range punch with this premium Wagner Tuning turbo outlet pipe and sports catalyst assembly. Built from corrosion-resistant 1.4301 grade stainless steel, this performance cat section is a direct, bolt-on replacement for the factory unit on early F-series N55 models. Expect reduced back pressure, lower thermal stress on the turbo and a noticeable increase in torque. We have fitted this upgrade many times at MJ Modifications and our customers love the response and driveability gains.
