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 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 an included controller ties into the factory harness for full, on-demand sound control.

The Gen 2 B58 (B58N) turbocharged inline-6 is one of BMW’s most capable modern engines, known for its immense tuning potential and smooth power delivery. However, factory catalysts restrict exhaust flow and limit turbo efficiency. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, improve turbo spool characteristics, and unlock a deeper, more aggressive exhaust tone — all while maintaining emissions compliance standards.

This small plug-and-play unit connects into the factory wiring harness and allows the driver full control of the exhaust valve whenever they want. For too long, enthusiasts have had to pay too much for command of their exhaust. We solved that issue. These controllers connect to the vacuum solenoid in the trunk to provide the driver control over their exhaust flap. Before purchasing, please ensure your car has a VACUUM-style exhaust valve. These DO NOT fit on electronic valves.

From the factory, the BMW i8 offers stunning looks and impressive performance, but its exhaust note leaves much to be desired. At Valvetronic Designs, we knew there was incredible sound potential hidden beneath the hybrid bodywork. Our full exhaust system transforms the i8’s character, letting the three-cylinder turbocharged engine breathe and deliver a unique tone, somewhere between a rally-bred triple and a Porsche flat-six, that turns heads everywhere you go.
