BMW M340i / M440i Valved Exhaust System

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

Good quality, Best for schools and shops.
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I bought this butyl repair patch and the quality is good. I brought it to the school where I’m learning automotive repair and used it as a teaching consumable. Many students tried it, and everyone thought it worked very well. One thing I would suggest for individual buyers: pay attention to the size combinations in the package. For most car owners, you may end up using only one size more often. Because of that, this mixed-size packaging is probably more suitable for schools, training programs, or auto repair shops where different sizes are needed regularly. Overall, it’s still a good quality product and performs exactly as expected.

Look very useful
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Haven't actually used them yet, but they look like the perfect way to fix a flat. As can be seen they come in various sizes depending on what you will need. All you need to get is some tire patch rubber cement and a good inner tire sealer (I picked up a can of Xtra Seal)

Saved me from buying a tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch, Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Took our ancient van on a trip to Florida (from IL) and wouldn't you know we picked up some debris in construction. I was able to plug it however the next morning it was flat again. This time I used 2 plugs to and we were able to get home on that. Realizing this wasn't what I wanted my wife driving around and I didn't wanna buy tires for a van with 250k on it I set out to find some internal patches. I pulled the tire off using a harbor freight bead breaker and some motion pro spoons, used vulcanizing Compound and a dremel and patched it right up. Once the tire is off its a really easy process and I just marked my tire and rim to keep the balance close when it went back together. All appears to be working perfectly with no leaks over the past few weeks. This cost way less than a new tire and now I have more for other holes in the future

worked great for Me
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I have only used two patches so far, and they have worked just fine, You do have to have some tools like a buffing wheel and the vulcanizing glue and a roller wheel to make these patches work as they should, but I am happy with these patches, especially since nobody will repair a motorcycle tire, so this is Your only way to fix them.
