We are proud to introduce our VRSF race & catted downpipe for your B58 X3 M40iX & X4 M40iX. This downpipe is THE best bang for the buck mod available. This downpipe is available in both race & catted configuration.
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our race or high flow 200 cell race cat which results in faster spool, an increase in power & a more aggressive exhaust note. Our downpipe features a full 4.5″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes. All VRSF downpipes are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (includes fitment).
Please note that the warranty on the catted downpipe is limited to two years.
