We are proud to introduce our VRSF 4.5″ downpipe for your B58 M240i/340i/550i/440i/740i & xDrive variants. 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.
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.
