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).
This item is not intended for use on the public road (track use ONLY) as it does not comply with UK emission standards.
- 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 a tune.
- VRSF Lifetime Warranty
- Fits both LHD & RHD with no modifications needed.
