Valvetronic Designs Valved Axleback Exhaust System for F22 & F3x BMW 2-Series / 3-Series / 4-Series

Valvetronic Designs Valved Axleback Exhaust System for F22 & F3x BMW 2-Series / 3-Series / 4-Series

Valvetronic Designs’ F-Chassis Valved Exhaust is the brand’s most refined system yet for BMW’s F-Series lineup. Engineered for performance, versatility, and longevity, V2 debuts a more robust valve design for optimal reliability, relocated hangers, and revised muffler internals that deliver a calmer, more refined note with the valves closed. A newly engineered cast Y-pipe maximizes flow and elevates tonal quality, producing a more engaging, sonorous soundtrack across the rev range. Designed for seamless fitment with the OEM mid-pipe or most aftermarket mid-pipes that follow factory dimensions, the system provides an uncompromising sound experience without sacrificing everyday usability.

Sound & Control

• Valvetronic Designs tunes the system for dual-character sound: with the valves open, it delivers a deep, raw, and aggressive tone with loud pops, sharp overrun snaps, and pronounced shift theatrics; with the valves closed, it returns to near-stock volume for quiet commuting and late-night driving. Integration with BMW’s factory drive-mode logic enables instant, in-cabin control over the exhaust’s character.

Why It Works

• Valvetronic Designs advances the platform with a new valve design that improves durability and response, refined closed-valve acoustics that lower volume and smooth the tone for daily comfort, and a cast Y-pipe upgrade that boosts flow and scavenging for a richer, more balanced soundtrack.
