We are proud to introduce the VRSF PWG catted downpipe for your N55 BMW. This downpipe is the best bang for the buck mod available.
 
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our high flow 200 cell race cat which results in faster spool, an increase in power and 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. All M135i & 335i models produced up to 07/13 require this 3.5″ version of this downpipe.
