VRSF - Stainless Downpipe Upgrade - BMW G2X M340i & M440i




We are proud to introduce our VRSF catless & 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 catless (race) & catted configuration.

Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our catless 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.


- Made from hand crafted, tig welded 4.5″ 304 grade stainless steel.
- Available with a 200 cell high flow cat.
- Fits RHD and LHD models with no modification necessary.
- Smooth radius bends to decrease turbulence and increase flow.
- Fits the stock catback as well as all aftermarket catbacks.

Please note that certain aftermarket exhaust systems may not comply with applicable US (including California) laws and regulations, and may therefore be prohibited for use on highways or roads, or on roads or vehicles otherwise subject to emissions control requirements. California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system.
