We are proud to introduce our VRSF catted downpipe for your N55 BMW. This downpipe is THE best bang for the buck mod available.
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 M135i & 335i models produced up to 07/13 require the 3.5″ version of this downpipe. M135 and 335i models produced after 07/13 require the 4″ model of this downpipe. All M235 and 435i models require the 4″ version of this downpipe. Please confirm by looking at your Turbo Wastegate. It is located on the lower passenger side of the engine next to the Turbo. See picture for reference.
Please note that while we do offer a lifetime warranty on the downpipes, we only offer a 1 year warranty on the ceramic coating as well as the catted versions.
