Dinan High Flow Midpipe for 340I 440I Cheap Affordable

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. 

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.
