Description:

The Valvetronic Designs Valved Exhaust System for the BMW G2X M340i and M440i is the ultimate upgrade for drivers who demand flexibility, performance, and an unforgettable exhaust note. Built with lessons learned from Valvetronic’s most celebrated systems, this setup delivers a raw, unfiltered sound when you want it—and refined civility when you don’t.

The system begins with a massive 3.5" midpipe, splitting into unrestricted dual 3" mandrel-bent runs that flow seamlessly to a set of signature Valvetronic Designs tips.
