The Dinan High Flow Mid-pipe for the F30 340i and F32 440i allows for an aggressive tone to be achieved out of the stock system. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that is hard to ignore. This full mid-section removes the factory center section, including both resonators, and replaces it with straight through 3.25" T304 stainless steel tubing for better flow, and sound while also reducing the weight by 3 pounds.

Features:

  • Deletes both resonators between the catalyst and the rear muffler.
  • Stock hydro-formed 80mm piping is replaced by 3.25" (82.6mm) mandrel-bent piping for free flow.
  • 100% 304 stainless steel construction.
  • Bolt-on installation.
  • Includes mounting hardware.
  • Weight savings over stock: Stock = 24 lbs; Dinan = 21 lbs.

Great! Wicked Sound!

Stock mufflers with 4.5 inch mrm downpipe and these midpipes sounds vicious. Loud on cold starts but quiets down in 30 seconds. Opens up the engine so much sounds very good. Highly recommend.

So happy you are enjoying your new parts Max, shoot me over some sound clips if you got any, would love to post them! sales@mrmperformance.com or you can DM us on instagram @MRM_Performance
