VRSF 3.5″ Catless Downpipe for N55 535i, 640i, 740i and X5/X6 E70/E71 (PWG)
Catless downpipe for the BMW F-series with the N55 (pneumatic wastegate). Gains instant power with this bolt-on.
The VRSF 3.5″ downpipe upgrade is THE best bang for the buck mod available for your N55 535i, 640i, 740i and X5/X6 E70/E71 (with Electronic Wastegate). By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is significantly reduced which results in faster spool, an increase in power & a more aggressive exhaust note. Our downpipe also features a unique CFD optimized cast merge collector which offers the smoothest turbo to mid pipe transition available.
Every VRSF downpipe is hand crafted from tig welded, mandrel bent, 304 grade stainless steel. High quality replacement hardware and mid-pipe gaskets are included although we highly recommend purchasing the optional turbo clamp and gaskets if your car has more than 60k miles.
