BMW G80 M3 / G82–G83 M4 Exhaust System

Single 3.5" Equal-Length Mid-Pipe + Optional Valved Axle-Back (T304 Stainless or Grade 5 Titanium)

Overview

The G80/G82/G83 is a phenomenal M car—its soundtrack just needs to catch up. Our single 3.5" equal-length mid-pipe unlocks the character the S58 deserves without requiring changes to the OEM rear section. Add the Valvetronic Designs valved axle-back for even more presence and control.

Compatible with OEM downpipes or free-flow front pipes, this system is engineered to deliver a higher-pitch, refined note with zero check-engine lights.

Sound With Free Flow Downpipes:

Sound With Stock Downpipes:

Why It Works

  • Equal-length design: Balances exhaust pulses for a smoother, higher-frequency tone.

  • Single 3.5" mid-section: Optimized flow for improved response and power throughout the rev range.

  • Modular by design: Pairs with OEM or aftermarket rear sections; upgrade path to our valved axle-back at any time.


Sound & Control

  • With stock downpipes: Noticeably crisper, more engaging tone without drone.

  • With our valved axle-back (optional): Quad-chamber muffler and OEM-style valves deliver daily-driver civility closed, and an aggressive, motorsport edge opened—at the touch of a button.

  • No CEL: System is designed to avoid check-engine lights.

Construction & Options

  • Materials: T304 stainless steel or ultra-light Grade 5 titanium.

  • Weight savings: Up to –57.8 lb (Titanium) or –24.7 lb (Stainless) vs. factory.

  • Craftsmanship: Precision TIG welds, fully mandrel-bent tubing, and included cross brace for rigidity.

  • Tips: Premium double-wall or single wall tips included.

Valve Integration

  • Electronic valve control with included controller for rapid open/close.

  • OEM integration available if you prefer factory valve control behavior.


Fitment

  • 2020+ BMW G80 M3

  • 2020+ BMW G82 M4 (Coupe)

  • 2020+ BMW G83 M4 (Convertible)

Installation Notes

  • Mid-pipe and axle-back can be installed independently.

  • When installing only a mid-pipe or axle-back, make the rear-section cut at the second dimple on the OEM pipe to ensure proper fitment.

  • 100% reversible—return to stock at any time.

  • CLICK HERE FOR INSTALL GUIDE

Compatibility Notice (V3 Systems)

  • V1/V2 components are not compatible with V3.

  • The V3 mid-pipe includes additional clearances at the downpipe connection and mid-section; small visible gaps prior to tightening are normal and by design.

What’s Included

  • Single 3.5" equal-length mid-pipe assembly

  • Cross brace

  • Optional: Valved axle-back with controller and tips

  • Hardware and clamps

Specifications

  • Tubing diameter: 3.5" mid-pipe; 2.75" axle-back

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.
