BMW F-Chassis Valved Axle-Back Exhaust System – Version 2
T304 Stainless Steel with Electronic Valves & Cast Y-Pipe
Overview
The Version 2 Valvetronic Designs F-Chassis Valved Exhaust is our most refined system yet for the BMW F-Series lineup. Designed for maximum performance, versatility, and longevity, V2 introduces a host of improvements, including a new valve design for optimal reliability, relocated hangers, and revised muffler internals for a more docile, refined tone when valves are closed.
A newly engineered cast Y-pipe maximizes exhaust flow and enhances tonal quality, delivering a more engaging and sonorous sound across the rev range. Whether paired with the OEM mid-pipe or most aftermarket mid-pipes matching factory dimensions, this system offers seamless fitment and an uncompromising sound experience.
Why It Works
New Valve Design: Improved durability and responsiveness over previous versions.
Refined Closed-Valve Acoustics: Reduced volume and smoother tone for daily driving comfort.
Cast Y-Pipe Upgrade: Increases flow and improves exhaust scavenging for a richer, more balanced tone.
Sound & Control
Valves Open: Deep, raw, and aggressive tone with loud pops, sharp overrun snaps, and pronounced gear-change sounds.
Valves Closed: Near-stock volume for quiet commuting or late-night driving.
Dynamic Drive Mode Integration: Fully compatible with BMW’s factory drive mode settings for instant sound control.
Construction & Quality
Material: Brushed T304 stainless steel for strength and corrosion resistance.
Craftsmanship: Precision TIG welds and full mandrel bends for optimal flow.
Tips: Sleeve-style exhaust tips for perfect alignment and premium appearance.

Reviews
Valvetronic axle back exhaust
"The exhaust itself is a work of art. Most people will never see it except for the tips. It came packaged very well and to my surprise they added 2 sets of tips, a nice tee shirt, decals, nice key chain and all the hardware needed. Everything looked excellent. The extra tips were the carbon fiber look and beautiful. The exhaust sounds fantastic with a little deeper tone. Nothing obnoxious. My only gripe is the passenger side outlet could not be centered. I can live with it for the moment. Otherwise a great system."

2014 BMW 428i (F32) N20
"Had to order a new rear bumper of course but obviously wasn’t an issue because I love the dual exhaust look. Had to saw off the muffler end of my stock mid pipe as seen in the YouTube videos provided. Only issue i had was not having clear instructions on the install for the amount of pieces provided, especially installing the pin for the valve control. Also the valve control harness has to travel from the passenger side across the muffler to the driver side where the valve control female end sits on the chassis. I’ve wrapped the harness, but the muffler keeps melting through, so I may have to order another. The exhaust tips are super clean and they made sure to properly protect your order before shipping, real happy about that."

Good tone
"The previous owner cut out everything passed the cats, I hated the cabin drone and cold starts. Now, this exhaust addition has made the cold starts bearable and the exhaust note while driving is a much better experience."
— Tito S. (5/5)
Bmw F36 exhaust
"Overall the exhaust has a great sound to it, not too loud and not too quiet. The only issue i ran into was with install, it says it will universally fit all F36 models, however one of the hangers was either not installed in the correct place, or not extended far enough because it was set about an inch off. This cause me to have to get a shop to weld an extension on."
— Evan V. (4/5)
For 2016 330i f30
"Exhaust came very fast, quality is really good the only down side I had is that it’s a little to quiet with the valves open, I have done a double resonator delete I do currently have stock downpipe and if I went catless I know it would be very much louder. When I put the valvetronic exhaust on my 2013 Subaru brz the only mode on that car was the exhaust and it was incredibly louder not sure why the bmw is significantly quieter, if you’re looking for something cheaper doing a res delete and muffler delete is the way to go to make this car loud now there needs to put a downpipe. It sounds great the way it is now it’s just not very loud to what I thought it was going to be. Still would highly recommend it’s a great exhaust but keep in mind to make it LOUD you do need a different downpipe"

Works with factory console button
"Can open and close from center console; closed and quiet on Comfort Mode, open and loud on Sport and Sport+ Mode. Sounds good. Very good. Had it on a week and pulled into carwash today, guy next to me was like "damn, I didn't know Bimmers growled like that. " Sometime they do ;)"
— TJ B. (5/5)
F36 Axleback
"One of my best purchases so far. Great value for the price, and it is the best-sounding exhaust for this chassis."
— Nicholas A. (5/5)
"Absolutely outstanding work put in by Valvetronic Designs. Ordered on Sunday night and it arrived on Thursday to Gibraltar in EUROPE. Not only was the delivery super quick, but I ordered the burnt exhaust tips, and they sent me those but also included the more expensive carbon fibre tips for free! Plus a load of goodies! As for the actual product I have yet to fit it but just from the service put in I have faith!"
— Ross (5/5)
The M235i sounds even better now
"Sounds awesome! The cold start tone has slightly changed to a deeper tone and With the valves open it just sounds perfect. My M235i feels even more alive than ever. Paired with a sports cat and res delete. The delivery was quick and on time considering I’m from the UK. Also love the freebies I received"
— Umar A. (5/5)
Q&A
Are there any guides or videos of how to install with the 4 cylinder adapter?
Hey Tyler! While we don't have a confirmed release date for those specific guides yet, our technical team is here to help. If you or your installer have any questions during the process, please reach out to us!
hello i have a bmw 2014 f34 335i with a n55 motor and i was wondering if u have or can make an exhaust for me.
This system is for the 335!
Hello. I have a bone stock 2013 bmw 328i with only a singular rear exhaust bumper. What do I need to do to provide two diffusers for the exhaust. And with purchasing this system do I have to purchase any other external pipes parts etc… Cheers 🇦🇺
Hey Leon, You will need to ensure that you have the 335/340 style rear diffuser / lower valance or the MSport bumper with dual outlets to allow for the dual exits! The system will come with everything needed for installation.
Will this fit a 2020 440i xdrive coupe?
yes!
Hi, how much louder is this than a standard exhaust, and also do you ship too uk
