The VRSF 4.5" catless downpipe for your B58 M140i/M240i/340i/550i/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).
- Made from handcrafted, TIG welded 4.5" 304-grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- Fits the stock catback as well as all aftermarket cutbacks that mate up with the OEM downpipe.
- CNC SS304 Stainless Steel Flange.
- Gains from 25-30hp with tune.
- VRSF Lifetime Warranty
- Fits both LHD & RHD with no modifications needed.
