Unlock the full performance and acoustic potential of your BMW M340i or M440i with the Valvetronic Designs Valved Sport Exhaust System — a no-compromise upgrade engineered specifically for G20, G22, and G26 chassis vehicles. This system is built for drivers who want complete control over their exhaust note, from quiet refinement to aggressive, motorsport sound.

With the valves open, the system unleashes a raw, high-performance tone featuring intense turbo spool, sharper overrun crackles, and a deep, aggressive character that transforms every drive. With the valves closed, the exhaust becomes docile and controlled, delivering near-OEM comfort with over 25 decibels of sound difference between modes. This dual-personality design makes it ideal for both spirited driving and everyday commuting.

At the heart of the system is a massive 3.5-inch mid-pipe that splits into dual 3-inch mandrel-bent pipes, ensuring unrestricted flow, maximum velocity, and optimized exhaust scavenging. Equipped with dual pneumatic-actuated valves, the system offers precise sound modulation, long-term reliability, and seamless integration with factory driving modes when desired. A set of signature Valvetronic Designs exhaust tips completes the rear aesthetic with a bold, performance-oriented finish.

Constructed entirely from high-grade T304 stainless steel, the system features precision TIG welding across all joints for maximum structural integrity and durability. Weighing 21.7 lbs less than the OEM configuration, the system provides improved vehicle dynamics and quicker throttle response. Installation is 100% reversible, making it ideal for leased vehicles or long-term enthusiasts who want flexibility without permanent changes.

Whether you’re carving canyon roads, enjoying a spirited drive, or heading to the office, the Valvetronic Designs Valved Sport Exhaust System ensures your M340i or M440i sounds and performs like the true performance machine it was built to be.
