Dinan High-Flow Mid-Pipes

Dinan high-flow mid-pipes upgrade the sound and enjoyment of your BMW. These pipes allow for an aggressive tone to be achieved from your stock system. Coupled with the associated Dinan exhaust, the sound is further perfected into an aggressive growl that's hard to ignore. This full mid-section removes the factory center section, including both resonators, and replaces it with straight-through T304 stainless steel tubing for better flow and sound—while also reducing the weight by 3 lbs. Order the kit designed for fitment on your vehicle model.
