VRSF race downpipe for your B58 Gen 1 M140i, M240i, 340i, 440i, 540i, 740i & xDrive variants.
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe 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 their “No Hassle” satisfaction guarantee (includes fitment).
