VRSF 3″ Cast Stainless Steel Catless Downpipes - 07-10 BMW 135i/335i (N54)

We are proud to introduce our VRSF 3″ Catless Downpipes for the N54 135i & 335i which now feature a cast stainless steel mouth. These 3″ downpipes are THE best bang for the buck mod available, with gains from 25hp & 30tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
