VRSF Downpipe Upgrade for 2015 – 2018 BMW X4 M40i & M40iX N55 F26

We are proud to introduce our VRSF Upgraded Down Pipe for your F26 X4 M40i/M40iX. This downpipe is THE best bang for the buck power mod available and it is available in either a race configuration or you can opt for our 200-cell high flow sport cat configuration. Back pressure is significantly reduced when replacing the restrictive catalytic converter in the factory downpipe which results in faster spool, increased horsepower & a more aggressive exhaust note.

Every VRSF downpipe is constructed from mandrel-bent, SS304 grade stainless steel and our flanges are precision machined in order to ensure proper fitment every time. We also include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment). For ultimate performance, we offer Cerakote’s best thermal barrier coating which helps keep the hot air inside the exhaust and out of the engine bay which decreases overall intake air temps along with engine and transmission oil temps. This High Temperature Ceramic Coating is made to withstand temperatures up to 1800F

Note: While we do offer a lifetime warranty on the downpipes, we only offer a 1 year warranty on the ceramic coating and high flow cat.
