BMW i8 Valved Exhaust System
Unlock the Hidden Sound Potential of the Hybrid Supercar
Overview
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.
Sound & Control
-
Valves Open: Deep, aggressive tone with exciting shift pops and overrun crackles—bringing drama and emotion to every drive.
-
Valves Closed: Quiet and refined, perfect for Eco mode and everyday commuting.
-
Factory Valve Integration: Works seamlessly with the i8’s drive modes—Sport mode opens the valves, Eco mode keeps them closed.
Performance Engineering
-
Free-Flow Design: A 3.0-inch mandrel-bent construction from front to tip minimizes restriction and maximizes sound quality.
-
Weight Reduction & Flow Gains: Less restrictive than the factory setup for improved throttle response.
-
Precision TIG Welding: Ensures exceptional durability and a flawless finish.
-
100% Reversible: Easily return to stock configuration at any time.
