Dinan High Flow Middle Exhaust for BMW M3 / M4 2021-2025


Note: 

  • Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed.

The Dinan Middle Exhaust for the G80 M3 and G82/G83 M4 is crafted for drivers seeking to amplify the car's sound profile while keeping the stock muffler for a budget-conscious enhancement. This middle exhaust transforms the acoustics with a bolder, louder, and sportier tone, adding a level of sophistication while remaining upgradeable for those who may want to add the Dinan axle-back exhaust in the future for an even more aggressive sound.

The system replaces the factory center section from the secondary catalysts to the axle-back, including both resonators, with a 3" (76mm) T304 stainless steel piping that improves flow and sound quality. A key element is the custom Dinan X-pipe, which promotes even exhaust flow between both banks, minimizing unwanted acoustic irregularities often present in the stock setup.

Key Features:

  • Enhanced Sound Profile:

    • Delivers a smoother, louder, and sportier exhaust tone by eliminating the factory resonators and adding an optimized X-pipe.
  • Improved Flow and Power:

    • Replaces stock 2.75" (70mm) piping with 3" mandrel-bent tubing, reducing restrictions and backpressure.
  • Custom X-Pipe Design:

    • The handmade X-pipe promotes balanced exhaust flow and a refined tone, outperforming common stamped X-pipes.
  • Lightweight Construction:

    • Weighs 17 pounds, a 5-pound reduction over the stock system.
  • High-Quality Build:

    • Constructed from durable 100% T304 stainless steel with factory-like fitment for longevity and performance.
  • Easy Installation:

    • Includes mounting hardware for straightforward, bolt-on installation.
