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.
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.
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.
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.
Valve System: OEM-style electronic valves with rapid open/close function; extension harness included.

"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 ;)"
"One of my best purchases so far. Great value for the price, and it is the best-sounding exhaust for this chassis."
"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!"
"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"
