For 2012 The BMW M5/M6 ditched the S85 V10 in favor of the far more advanced S63 twin-turbo V8. This change lost the M5/M6's incredible sound character,(seriously, the E60 M5 was just a race car powertrain wedged inside a 5 series shape) but we have developed a system that will make you forget that the S85 even existed. Connecting to stock or aftermarket free-flow exhaust downpipes, the valved exhaust measures 3.0 inches from inlet to outlet. This system features a vast crossover section x pipes for ample exhaust scavenging and power gains. After the X-pipes the exhaust gases pass through our valved mufflers before exiting through a beautiful set of tips that can be customized to your choosing. The valves are controlled via a key fob and a small wiring harness that plugs into the factory valve control giving you 100% control.
