VRSF BMW B58 4.5" Catless Downpipe (M140I, M240I, 340I, 440I & 540I)

The VRSF 4.5" catless downpipe for your B58 M140i/M240i/340i/540i/440i/740i & xDrive variants. This 4.5" downpipe is the best value modification available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in a faster spool, an increase in power & a more aggressive exhaust note.

The VRSF catless 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).
