The Palenon Performance valve-controlled cat-back exhaust gives the B58-powered G20 M340i and G22 M440i more flow, a better sound and adjustable volume through electronic valves.

Why you need it

Higher flow improves throttle response, and the valves let you choose between a quieter cruise and a deeper, more aggressive tone.
