VRSF Catless Downpipes RWD N54

We proudly stock the 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 paired with a DME tune. By replacing the restrictive catalytic converters in the factory downpipes, back pressure is significantly reduced. This results in a faster turbo spool, an increase in power, & a more aggressive exhaust note.

Fits 2007-2010 BMW 135i, 1M, 335i & 335IS with the N54 Engine.
