VRSF 3″ Cast Stainless Steel Downpipe

VRSF 3″ Cast Stainless Steel Downpipe Upgrade N54 V2 2007 – 2010 BMW 335i / 2008 – 2012 BMW 135i

We are proud to introduce our VRSF 3″ High flow Downpipes for the N54 135i & 335i. These 3″ downpipes are THE best bang for the buck mod available, with gains from 30hp & 35tq when when paired with a DME remap. By replacing the restrictive catalytic converters in the factory N54 downpipes, back pressure is significantly reduced which results in faster spool, an increase in power & a more aggressive exhaust note.
