BMW 440i Performance Exhaust - Dinan - High Flow Mid-Pipe - ’16–’20. Purpose-built to deepen the exhaust note and improve flow while retaining factory fitment.
This full mid-pipe swaps the factory center section for straight-through 3.25" (82.6mm) mandrel-bent 304 stainless, removing both resonators and the hydro-formed 80mm tube. Pair with the Dinan Free Flow Axle-Back for the most pronounced growl, or keep the stock rear muffler for a more restrained edge. Hardware is included and installation is bolt-on. Confirmed with the stock system or Dinan axle-back; other axle-backs are not guaranteed. Typical weight savings: about 3 lbs (24 lbs OE vs 21 lbs Dinan).
