VRSF B58 Downpipe Upgrade 2016+ BMW M240i/340i/440i/540i/740i & xDrive

This downpipe is THE best bang for the buck mod available for the B58 engine. This downpipe is available in both catless (race) & catted configurations.

Backpressure 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 handcrafted 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.
