Dinan High Flow Mid-Pipe - 2016-2020 BMW 340i/440i
High Flow Exhaust Intermediate Mid-Pipe; w/3.25 in. T304 Stainless Steel Tubing;
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.
- Weight savings over stock: Stock = 24 lbs; Dinan = 21 lbs.
- Includes mounting hardware.
- 100% 304 stainless steel construction.
- Stock hydro-formed 80mm piping is replaced by 3.25" (82.6mm) mandrel-bent piping for free flow.
- Deletes both resonators between the catalyst and the rear muffler.
- Bolt-on installation.
