VRSF - Stainless Steel Catless Downpipe - BMW N55 (F-Chassis)


We are proud to introduce the VRSF Catless Downpipe for your N55 BMW (F-Chassis). This downpipe is the best bang for the buck mod available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.

This catless downpipe is hand crafted from mandrel bent SS304 grade stainless steel and the turbo flange is precision CNC machined out of billet 304 grade stainless steel.  All VRSF products include a lifetime warranty as well as their "No Hassle" satisfaction guarantee (including fitment). Please note that 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.

Ceramic Coating services are also available on these, utilizing Cerakotes High Temperature Ceramic coating, made to withstand temperatures up to 1800F. Please note that while VRSF offers a lifetime warranty on the downpipes, they will only offer a 1 year warranty on the ceramic coating services due to the nature of the product.
