Description
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 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.
