For more information, visit www.P65warnings.ca.gov.The Dinan High Flow Mid-Pipe (D660-0068) is a performance-mandated exhaust upgrade for the 2017-2021 BMW M240i (F22), engineered to introduce a more aggressive and perfected tone, particularly when paired with the corresponding Dinan axle-back system. This full mid-section kit removes the factory center section, including both resonators, and replaces the stock 80mm piping with straight-through 3.25" (82.6mm) T304 stainless steel tubing. This upgrade significantly improves exhaust gas flow and sound while also achieving a 3lb weight savings over the stock 24lb system.
Features:
-
Resonator Deletion: Deletes both resonators located between the catalyst and rear muffler for a significant increase in volume and a more aggressive growl.
-
Optimized Flow & Diameter: Stock 80mm piping is replaced by 3.25" (82.6mm) mandrel-bent piping for superior, restriction-free flow.
-
Weight Reduction: Achieves a 3lb weight saving (reducing the stock weight from 24lbs to 21lbs).
-
Structural Quality: Built from 100% 304 stainless steel construction for long-term durability and corrosion resistance.
-
Installation: Designed for a simple, direct bolt-on installation with all mounting hardware included.
