Product Details

The Dinan D660-0068 High Flow Mid-Pipe is a performance exhaust upgrade designed specifically for 2017-2021 BMW M240i models. This mid-pipe section replaces the factory restrictive dual-resonator design with free-flowing mandrel-bent tubing to unlock improved exhaust flow and a more aggressive exhaust note.

Key Features:

  • 100% 304 stainless steel construction for superior durability and corrosion resistance
  • Mandrel-bent 3.25" (82.6mm) piping replaces stock 80mm hydro-formed tubing for optimized flow
  • Deletes both factory resonators positioned between the catalytic converter and rear muffler
  • Weight reduction of 3 lbs compared to stock (Dinan: 21 lbs vs Stock: 24 lbs)
  • Direct bolt-on installation with all necessary mounting hardware included

This mid-pipe delivers noticeable improvements in throttle response and exhaust sound while maintaining compatibility with both stock and aftermarket exhaust components. The mandrel-bent design eliminates restrictions caused by the factory crush-bent piping and resonator chambers, allowing your turbocharged B58 engine to breathe more efficiently. Professional installation is recommended to ensure proper fitment and alignment with adjacent exhaust components.

.

Easy shopping, good prices. Would like just a little more specific information on the item descriptions.

Bought a Husky gearbox for my Silverado, great price and a great product. Install was simple and the fit was perfect. Gone are the days of opening the rear door and all the items under the seat sliding out. Great for my hitch, tow straps, jumper cables and other miscellaneous must haves in a truck. Great seller the price was the best on the net even with shipping. Item arrived quick and in perfect shape. Thanks!!

The ordering process was simple and user friendly. The pricing was the lowest I could find for a brand new AMP Powerstep for my Ford F150. The tracking number was provided and the item is scheduled for FedEx ground delivery in 3-days.

Autoplicity had the best price on the Motive brake bleeder I needed, and they shipped quickly.
