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.
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.
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.

Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
