VRSF E90/E92 335xi N54 Downpipes, xDrive | 2007-2010

The VRSF 3-inch race downpipes are made for the all-wheel-drive N54 E90 sedan and E92 coupe, sold as the 335xi and later the 335i xDrive. The xDrive front axle changes the routing, so these pipes are built specifically to clear it.

What It Does

Downpipes are one of the best-value upgrades for the N54. Removing the factory converters cuts back pressure right behind the twin turbos, so they spool faster and the car pulls harder. VRSF measures 25 to 30 hp with a tune, and the exhaust note becomes much more aggressive.

Materials and Construction

The pipes are mandrel bent and TIG welded from 3-inch 304 stainless steel with smooth radius bends, and the flanges are CNC machined from 304 stainless. Grade 12 installation hardware and two mid-pipe gaskets are included. VRSF recommends replacing turbo clamps and gaskets every 60,000 miles.
