Valvetronic Designs BMW G20/G22 330i/430i Valved Axleback Exhaust System

Transform the sound and performance of your BMW G20 or G22/G23 with the Valvetronic Designs Valved Axleback Exhaust System — engineered for enthusiasts seeking premium sound, OEM integration, and flexible driving modes without compromising comfort or factory drivability.

This axleback setup is inspired by Valvetronic Designs' renowned F-chassis system and delivers an ideal balance between quiet refinement and aggressive tone. With factory-style valve control and high-quality TIG welds throughout, this exhaust system offers a truly OEM+ upgrade for your BMW. Designed to work seamlessly with OEM drive modes, the system gives you the power to control your exhaust note — silent when needed, loud when desired.

When the valves are closed, exhaust gases are routed through a quad-chambered muffler to reduce sound levels to near-stock, making it ideal for early morning starts or neighborhood driving. Once the valves open, the system bypasses the muffler entirely, delivering a thrilling, high-flow exhaust tone that remains drone-free and enjoyable on long drives. Whether you're combining this with other free-flowing performance parts or running it as a standalone upgrade, the Valvetronic Axleback is engineered to exceed expectations.

This system is 100% reversible and uses the factory mounting points and cut locations for a precise, clean installation. The 3.5” tips provide a bold yet refined rear-end look, perfectly complementing the aesthetics of the G2X platform.
