We are proud to introduce our VRSF catless & catted downpipe for your N55 BMW. This downpipe is THE best bang for the buck mod available. This downpipe is available in both catless (race) & catted configuration.
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our catless or high flow 200 cell race cat 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 and our CNC precision machined flanges are also constructed from billet 304 grade stainless steel. All VRSF products include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment). M135 and 335i models produced after 07/13 require this 4″ model of this downpipe. All M235 and 435i models require this 4″ version of this downpipe. Please feel free to contact us with the last 7 of your VIN if you need help determining exactly which version of the downpipe your car requires.
