We are proud to introduce our VRSF race & high flow catted downpipe for your B58 M240i, 340i, 440i, 540i, 740i & xDrive variants. These downpipes are THE best bang for the buck mod available for your B58 and they’re available in both race & high flow configurations. 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 one year.
