BMW N63R / N63B G30 M550i, G12 750i, M850i Catless Race Downpipes

Palenon Performance high-flow race downpipes for the N63R and N63B 4.4L twin-turbo V8 remove the restrictive factory catalytic converters on G-chassis BMWs for quicker turbo response and a deeper, more assertive exhaust tone.

Why you need it

Lower backpressure means more horsepower and torque. Palenon quotes up to 50+ hp and 60+ lb-ft at the wheels when properly tuned.

Good to know

Intended for off-road and competition use only. Not legal for use on public roads in many areas. Catless downpipes will set a check engine light; the CEL delete kit may not clear it on 2019+ vehicles. A supporting tune is recommended. F-chassis N63 / N63TU cars need a different downpipe.
