VRSF - Stainless Steel Downpipe - BMW B58




We are proud to introduce the VRSF 4.5" catless downpipe for your B58 engine. This 4.5" downpipe is THE best bang for the buck mod available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.

This 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 hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as their "No Hassle" satisfaction guarantee (includes fitment).

- Made from hand crafted, 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 catbacks that mate up with the OEM downpipe.
- CNC SS304 Stainless Steel Flange.
- Gains from 25-30hp with tune.
- VRSF Lifetime Warranty
