Dinan High Flow Middle Exhaust for BMW M550i xDrive 2018-2023


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 G30 M550i is designed to bring out the full potential of the V8’s sound, adding a bold, aggressive tone and a boost in volume over the stock setup. This complete mid-section upgrade replaces the factory center section, including the resonator, with a 3" T304 stainless steel tube for enhanced flow and performance. The system also features an intricately crafted X-pipe, designed to optimize flow between exhaust banks and eliminate irregularities in sound common in stock exhausts.

Key Features:

  • Enhanced Sound Profile:

    • Delivers a sportier, smoother, and fuller exhaust note by deleting the factory resonator and incorporating an X-pipe.
  • Optimized Flow:

    • Replaces the stock 70mm piping with 3" (76mm) mandrel-bent tubing, ensuring maximum exhaust flow and reduced backpressure.
  • Premium Construction:

    • Constructed from 100% T304 stainless steel for superior durability and resistance to corrosion.
  • Improved Exhaust Dynamics:

    • The custom X-pipe promotes even flow to both sets of tips, refining the exhaust note and creating a balanced, aggressive tone.
  • Straightforward Installation:

    • Bolt-on design with included mounting hardware for a hassle-free fit.
