BMW N55 F10 535i / 640i / 740i / X5 / X6 Catless Race Downpipe

The Palenon Performance N55 downpipe is built for F-chassis BMW 535i, 640i and 740i plus the X5 and X6 35i, in both electronic wastegate (EWG) and pneumatic wastegate (PWG) versions.

Why you need it

Removing the restrictive factory cat cuts backpressure for faster spool and sharper throttle response. Palenon quotes 25-30 hp with a supporting tune, plus a more aggressive exhaust tone.
