AC Schnitzer Downpipes with Sports Catalysts for many BMW Vehicles

The AC Schnitzer downpipe is made entirely of high-quality stainless steel. It has two lambda sensor connections and an integrated sports catalytic converter with 300 cell/inch (series: 600 cell/inch). The lower number of cells per inch (cpsi) compared to standard catalytic converters means that exhaust gases are purified faster, exhaust back pressure is reduced and the engine achieves higher performance.
