VRSF N55 Downpipe Upgrade for 2012 - 2018 BMW M135i, M235i, M2, 335i & 435i F20 / F21/ F22 / F30 / F32 / F33 / F87

We are proud to introduce our VRSF catless & catted downpipe for your N55 BMW. This downpipe is THE best bang for the buck mod available. This downpipe is available in both catless (race) & catted configuration.

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

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 below for reference.
