BMW F30 340i B58 Valved Cat-Back Exhaust System

The Palenon Performance valve-controlled cat-back exhaust for the F30 340i B58 is built for more flow, an aggressive sound and adjustable volume through electronic valves.

Why you need it

It reduces backpressure, sharpens throttle response and drops over 60 lbs versus the stock exhaust. Palenon quotes 30+ hp and 25+ tq when properly tuned.
