BMW i8 1.5L Catback Anodized Gold T304 SS, Anodized Gold 3.5" Tips

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.

• T304 stainless steel construction finished in anodized gold.
• Fully mandrel-bent 3.0-inch T304 stainless steel construction
• Works with factory exhaust valve controls and drive modes
• Weight Reduction & Flow Gains: Less restrictive than the factory setup for improved throttle response.
• Paired with Valvetronic Designs signature gold exhaust tips
