BMW G20/G22 330i/430i Valved Axleback Exhaust System
Welcome to the next revelation in G2X exhaust systems! For this axleback version we opted to create a similar system to our infamous F Chassis valved system; allowing you to customize your setup with additional exhaust modifications to obtain the desired sound you may be looking for; all with the flexibility of OEM valve integration for zero compromises! TIG welded to perfection, this system utilizes factory mounting positions and cut points for a truly OEM+ final result. Tips measure 3.5 inches for a clean appearance in the rear bumper of your BMW.
With valves closed, all exhaust gases are forced to be routed through our quad-chambered muffler, quieting down the exhaust tone to stock levels for those early morning startups, providing an unparalleled level of flexibility when needed. Open it up however and the tone completely changes as the exhaust gases bypass the muffler and go straight out the other side providing an enjoyable, drone-free experience. Our goal with this axle-back setup is to give the driver the ideal sound experience. Whether you want to combine this modification with other aftermarket free-flow components or this is the only exhaust modification you do, great sound and great flexibility comes guaranteed. At Valvetronic Designs, we do not compromise. You shouldn't either when choosing the best exhaust system for your BMW.
