BMW G16 M850i Gran Coupe / Alpina B8 Valved Exhaust System

Full T304 Stainless Steel System with OEM Valve Integration


Overview

The BMW G16 M850i Gran Coupe and Alpina B8 deliver incredible performance and refinement—but their stock exhaust note leaves room for excitement.
Our Valvetronic Designs Valved Exhaust System is engineered specifically for this platform to enhance presence, sharpen tone, and add measurable performance gains.

This full system bolts directly to the OEM downpipes or can be paired with a free-flow front race pipe setup. Valve operation integrates seamlessly with the factory Sport and Sport+ driving modes, allowing instant sound control from the driver’s seat. As a direct OEM replacement, it installs with no modifications and is guaranteed to deliver a richer, more engaging soundtrack through the entire rev range.


Why It Works

  • Bespoke Platform Design: Engineered specifically for the G16 M850i and Alpina B8 for perfect fitment and optimized acoustics.

  • Full Mandrel-Bent Construction: Maximizes exhaust flow for improved throttle response and power.

  • OEM Valve Integration: Retains factory valve functionality for quiet cruising or aggressive sound on demand.


Sound & Control

  • Valves Closed: Maintains refined, comfortable tone for daily driving.

  • Valves Open: Delivers a deeper, more aggressive note with added volume and character.

  • OEM Integration: Controlled via Sport and Sport+ modes—no extra remotes or wiring required.

Questions?

WE HAVE ANSWERS

How long til' I get my order?

Small items arrive to you in under 1 week

Larger products like full suspension kits must ship freight and can take 1-3 Weeks

Are Installation Instructions Included?

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

What is your return policy if the part doesn’t fit or isn’t what I expected?

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.

Do your parts come with a warranty?

All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.

I found a better price somewhere else, can you beat it?

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.

Do you give out discounts or sponsorships?

NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
