BMW's move from the S85 V10 to the S63 twin-turbo V8 brought big gains in efficiency and speed-but the factory exhaust left the soundtrack behind. The Valvetronic Designs Valved Exhaust System restores the drama, delivering a sharper, more engaging tone with genuine GT composure when you want it.

Connecting to OEM or aftermarket free-flow downpipes, this system runs 3.0 inches from inlet to outlet and features a large X-pipe crossover for superior scavenging and response. Exhaust flow then passes through our valved mufflers, exiting via your choice of premium tips. A vacuum-actuated valve system with included controller ties into the factory harness for full, on-demand sound control.
