2016-2020 BMW 340I/440I Mid Pipe by Dinan
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.
