Valvetronic Valved Sport Axle-Back Exhaust System - 3.5" Black Tips - BMW F22 F30 F32/33/36 N20 N55 B46 B58

Product Details

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

Installation Notes

• 100% reversible—return to stock at any time.
• For non-M Sport or 4-cylinder applications, an M-Sport style diffuser is necessary for dual tip fitment
• B58/B46 Owners: Requires minor mid-pipe modification – Learn More: https://valvetronic.com/blogs/blog/f-chassis-b58-4cylinder-midpipe-modification
