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

Unethical book
Format: Paperback
Had to get this book for a required class. This book is unreadable. It is written in an outdated language of old philosophers. The book itself if unethical. It starts out with one inch margins then once you get into it they switch to half inch margins. That's deceitful. Everyone I have talked to in the class can't stand the book. l read it because I have to, but I'm not getting anything out of it. Humanity is certainly lacking ethics these days, but this book is a waste of my time and if I'm struggling reading it, I doubt anyone who actually needs to read this book will make it through more than a page.
