🚚Ships from Dinan — this item ships direct from the
manufacturer. It usually goes out quickly, but because it leaves their warehouse rather
than ours, delivery can take a little longer than our in-stock parts.
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
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.
Please verify exact fitment (engine, submodel, and trim) before purchasing.
