We are pleased to introduce our VRSF catless downpipe, specifically designed for your N55 F-Chassis BMW. This downpipe is one of the best performance mods available for the price.

Our catless downpipe effectively eliminates the restrictive catalytic converter found in the factory downpipe, reducing back pressure and allowing for faster spool, increased power, and a more aggressive exhaust note.

Crafted by hand from mandrel-bent SS304 grade stainless steel, our downpipes feature CNC precision machined flanges made from billet 304 grade stainless steel. Please note that all M135i and 335i models manufactured up to 07/13 require the 3.5" version of this downpipe, while those produced after 07/13 require the 4" model. For M235 and 435i models, the 4" version of this downpipe is required. To ensure proper fitment, please confirm by checking your Turbo Wastegate, located on the lower passenger side of the engine, next to the Turbo.
