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.


Fitment

  • 2014 – 2020 BMW i8


Features

  • Integrated valved cat-back system with free-flow front section

  • Fully mandrel-bent 3.0-inch T304 stainless steel construction

  • Works with factory exhaust valve controls and drive modes

  • Deep, aggressive exhaust tone with unique triple-cylinder character

  • Precision TIG welds for maximum strength

  • 100% reversible installation

Narrow and small
Size: 10.5, Color: Black/City Skyline/Egret
I mostly chose these due to the foam rubber soles, as I was looking for a more comfortable sneaker. They are more comfortable and the quality looks decent, too, although I wish the leather wasn't so shiny. The fit is quite narrow, and while they're okay for my narrow feet, I still wonder if the wider fit would have been better. This is my 2nd pair of Cole Haan sneakers and the first were too small. So this time I ordered the next size up and the fit is not much different, so I'd say they run small all around. Despite that, they're big enough and are still quite comfortable. Finally, the laces are too short. This is probably by design, so they're not dangling around, but I find them difficult to tie. They're nice, waxed laces, but they just need to be long enough to work with.
