Description
Revise the center exhaust section on 2017-2021 BMW M240i with the Dinan Stainless Steel High Flow Mid-Pipe.
The replacement section changes the routing and acoustic behavior ahead of the rear muffler. Its contribution depends on the rear exhaust and other components already fitted, so it should be selected as part of the complete exhaust combination.
Technical details
- Section: middle / connecting exhaust pipe.
- Nominal tubing size: 3.25-Inch.
- Construction: stainless steel.
- Listed vehicle application: 2017-2021 BMW M240i.
- Manufacturer part number: D660-0068.
Fitment and installation
- Confirm compatibility with the existing rear exhaust and any required cutting or joining procedure. The rear muffler / axle-back is a separate component unless explicitly specified in the kit contents.
- A stronger exhaust note does not mean zero cabin resonance; other modifications can change the sound substantially.
