VRSF 2012 – 2018 BMW M135i, M235i, M2, 335i & 435i F20/F21/F22/F30/F32/F33/F87 Downpipe

VRSF is proud to introduce its catless and catted downpipes for your N55 BMW. This downpipe is THE best bang for the buck mod available. It is available in both catless (race) and catted configurations.

Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with VRSF’s catless or high-flow 200-cell race cat, which results in a faster spool, an increase in power & a more aggressive exhaust note.

VRSF downpipes are hand crafted from mandrel bent SS304 grade stainless steel, and VRSF’s CNC precision machined flanges are also constructed from billet 304-grade stainless steel. All VRSF products include a lifetime warranty and their “No Hassle” satisfaction guarantee (including fitment). 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 the picture below for reference.

Note: VRSF also offers ceramic coating services utilizing Cerakote High-Temperature Ceramic coating, made to withstand temperatures up to 1800F. VRSF uses Cerakote’s best thermal barrier coating, which helps keep the hot air inside the exhaust and out of the engine bay, which decreases overall intake air temps along with engine and transmission oil temps. Please note that while VRSF offers a lifetime warranty on the downpipes, VRSF only provides a 1-year warranty on the ceramic coating and the catted versions.
