Valved Axle-Back Exhaust System

The Valvetronic Designs Valved Axle-Back exhaust system for the BMW G2X platform offers a significant upgrade in sound customization and performance. Constructed from premium T304 stainless steel and precision TIG-welded, this system ensures durability and maximum flow. It features a quad-chambered muffler that routes exhaust gases for a quiet, stock-level volume when the valves are closed, perfect for early morning starts or stealthy commuting. When the valves are opened, they bypass the muffler, freeing up the exhaust flow for a more aggressive and engaging tone without introducing unwanted cabin drone. The 3.5" outlet tips are designed to perfectly fill the rear bumper, providing a refined, performance-oriented look. It integrates with your BMW's factory drive modes for instant control over the exhaust note. An extension harness is included for plug-and-play operation, and the system is 100% reversible, allowing you to return to the stock setup at any time. This Valved Axle-Back exhaust system is compatible with the 2019–2024 BMW 330i (G20) and 2019–2024 BMW 430i (G22 / G23). It is also compatible with the 330e and 2025 models, though these may require modifications. It is not compatible with the M440i; however, Valvetronic Designs offers a full G20 catback system for that model.
