Dinan's Free Flow axle-back exhaust for the F80 M3 and F82/F83 M4 is dyno tuned for maximum flow with minimum backpressure, adding roughly 5 horsepower. Twin 76mm secondary valves are 45% less restrictive than the OE valves and stay computer controlled, quiet at low speed and open fully under load, so tone can still be adjusted through the M-Drive settings. The full system is 100% 304 stainless steel and about 3 pounds lighter than stock, using the factory brackets and hangers for a precise fit. It exits through quad 3.5 inch laser engraved black ceramic coated tips.
