13-19 BMW 135i 335i 435i M2 N55 Catless Downpipe F32/F33/F36/F22/F23

13-19 BMW 135i 335i 435i M2 N55 Catless Downpipe F32/F33/F36/F22/F23Circuit Werks catless downpipe for the N55 BMW. Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our catless which results in faster spool, an increase in power and more aggressive exhaust note. All M135i & 335i models produced up to 07 13 require the 3. 5 version of this downpipe that we offer as well. The 3. 5" uses a Pneumatic Wastegate M135 and 335i models produced after 07 13

This allows trucks with air bags to lay frame without fear of damaging their exhaust system

will not warp as easy as other flanges that are cast then machined
