We are proud to introduce the VRSF high flow catted downpipe & mid pipe combo for your X5D BMW. This combo is THE best bang for the buck mod available for your X5D. Back pressure is significantly reduced by replacing the restrictive catalytic converter in the factory downpipe with a high flow 200 cell catalytic converter which results in faster spool, an increase in power & a more aggressive exhaust note.

VRSF downpipes are hand crafted from mandrel bent SS304 grade stainless steel tubing and our CNC precision machined flanges are also constructed from 304 grade stainless steel billet. Please note that the warranty on the catted downpipe is limited to 1 year.
