VRSF 4.5″ Catless Downpipe For B58 G30 series

The VRSF 4.5″ downpipe upgrade is THE best bang for the buck mod available for your B58 equipped model GXX series BMW. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is significantly reduced which results in faster spool, an increase in power & a more aggressive exhaust note. The downpipes also features a unique CFD optimized cast merge collector which offers the smoothest turbo to mid pipe transition available.

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 hand crafted from SS304 grade stainless steel and include a lifetime warranty.
