Discount code here! Save big money on Valvetronic. Valvetronic SS & Titanium Equal Length Valved Exhaust for F8X M3/M4 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.
