• Pipe diameter: Make sure the tips you choose have the same pipe diameter as your M440i's exhaust pipes.

Step-by-Step Installation Instructions

Now that you have everything you need, let's get started with the installation process:

7. Tighten the bolts: Use a wrench to fully tighten the bolts that secure the exhaust tips.
8. Enjoy your new exhaust tips: Take your M440i for a drive and enjoy the improved sound and look of your exhaust system.
