VRSF 3.5″ Stainless Steel Race & High Flow Catted Downpipe

For your 2011 – 2017 BMW X3 & 2014 – 2018 X4 with the N55 Engine

We are proud to introduce our VRSF 3.5″ downpipe for your N55 F25/F26 BMW X3 & X4. This direct bolt on downpipe is THE best bang for the buck mod available for your BMW. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note. We also offer a catted version of this downpipe which features a 200 cell high flow catalytic converter which offers the same increase in exhaust note, faster spool with a slight difference in HP. Both options will fits RHD and LHD models with no modification necessary.

This downpipe features a full 3.5″ stainless steel design and is hand crafted from SS304 grade stainless steel. Like all VRSF products we also include a lifetime warranty as well as our “No Hassle” satisfaction guarantee which includes fitment and defects. We also offer ceramic coating services on the race downpipe which utilizes Cerakote’s High Temperature Ceramic Coating, made to withstand temperatures up to 1800F.

Please note that the warranty on the catted downpipe is limited to two years. The warranty on the ceramic coating is limited to 1 year while the downpipe itself includes a lifetime guarantee.

Note: Will only fit PWG cars with 3.5″ downpipe outlet. Please contact us if you need assistance confirming if you are PWG or EWG.
