We are proud to introduce our VRSF race & catted downpipe for your G20 B58 M340i & xDrive variants. 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 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).

VRSF 4.5″ G20/G22/G26/G42 B58 Stainless Steel Downpipe

  • Made from hand crafted, tig welded 4.5″ 304 grade stainless steel.
  • Fits RHD and LHD models with no modification necessary.
  • Smooth radius bends to decrease turbulence and increase flow.
  • Fits the stock cat back exhaust as well as all aftermarket cat back.
  • Gains from 25-30hp with tune.
