VALVETRONIC BMW M3/M4 F8X EQUAL LENGTH VALVED EXHAUST

Welcome to the Valvetronic Designs catback exhaust system for the F8x platform, or in other words, the solution to the F8x sound problem. For years enthusiasts have been wanting to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released back in the late portions of 2014 we all knew there was an amazing sound lying under all the rasp. Our mission has been to find this hidden sound and allow all F8x owners to enjoy it. This full catback starts as a dual 2.5-inch setup featuring 2 resonators to eliminate the unwanted rasp. From there the system travels back and merges into a single 3.5 inch pipe. After the merge, the exhaust either exits out of the Drivers side exhaust tips when the valves are open or passes through our quad chambered muffler and out of the passenger side exhaust tips when the valves are closed for a lower volume experience. This system mounts up to factory mounting points and is a direct bolt-on. No cutting or welding necessary. Its time to make the F8x sound like it always should have.
