Lease for as low as $/week
BMW M340i / M440i Valved Exhaust System
3.5" Midpipe, Dual 3" Axle-Back, Pneumatic Valves
Overview
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 our most celebrated systems, this setup delivers a raw, unfiltered sound when you want it—and refined civility when you don’t.
From the moment you start the engine, you’ll experience the full potential of the B58 powerplant. 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.
Sound & Control
-
Valves Open: Expect maximum drama—turbospool that’s impossible to ignore, aggressive overrun pops, and a motorsport-inspired tone that sings from idle to redline.
-
Valves Closed: The volume drops by over 25 decibels, transforming the system into a docile, daily-drivable setup perfect for early morning starts or long highway cruises.
Why This System Stands Out
-
Maximum Flow Design: 3.5" front section feeding dual 3" rear piping for unparalleled performance and tone.
-
Unmatched Versatility: Dual pneumatic valves deliver instant transitions from stealth to sport.
-
Premium Build Quality: T304 stainless steel construction with precision TIG welds ensures durability and a flawless finish also available in Grade 5 titanium
