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

Installation Notes

  • 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.

Great Fit and Noticeable Air Quality Improvement
Style: 12x24x1
I purchased the Filterbuy 12x24x1 MERV 8 air filters and have been very happy with them so far. They fit perfectly in my HVAC system without any gaps or issues during installation. After replacing my old filters, I noticed the air in my home feels cleaner and there seems to be less dust settling around the house. They do a good job of capturing everyday particles and allergens while still allowing good airflow. Overall, this is a reliable and cost-effective 4-pack of filters. Solid quality, easy to install, and a noticeable improvement in air freshness. I’ll definitely be ordering again.
