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.
