3" SS304 Race Downpipes

The VRSF 3″ stainless steel race downpipes are engineered to enhance the performance of your 2007 to 2011 N54 E90 & E92 335xi. These downpipes represent a significant upgrade by removing the factory's restrictive catalytic converters, which directly reduces exhaust back pressure. This modification is celebrated as a top-value performance enhancement, capable of yielding gains of 25-30 horsepower when paired with a tune. The resulting decrease in back pressure not only contributes to faster turbo spool times but also leads to a noticeable increase in overall power output. Furthermore, the removal of catalytic converters results in a more aggressive and desirable exhaust note. The construction features mandrel-bent, tig-welded 3″ SS304 stainless steel piping with smooth radius bends to ensure optimal flow and minimal turbulence. The flanges are CNC machined from SS304 stainless steel for durability. Included with your purchase are Grade 12 installation hardware and two mid-pipe gaskets to facilitate installation. VRSF also backs these downpipes with a lifetime warranty and a No Hassle satisfaction guarantee. For optimal performance and longevity, it is recommended to replace turbo clamps and gaskets every 60,000 miles.
