Just wanted to make a quick post after installing the M Performance Exhaust today.
When doing my research I saw a great amount of mixed reviews throughout various forums.
I’m here to tell you that it is enough! The deeper tone is rich and the brapp when up shifting is intoxicating! I’m completely in love down below I will post ever single part you’ll need with detailed descriptions of what comes with each part number.

Part # 18302431035 - M Performance Muffler

Box comes with Muffler, Dummy Flap Actuator and Clamp.

Part # 18302449941 - Chrome Tips for Muffler

You get two chrome M Performance Exhaust Tips and Two Clamps.

Part #- 51128067763 - M550i Rear Bumper diffuser to fit the new bigger tips.

All get it the rear diffuser / valence / bumper cover
And you can transfer your old red reflectors from the existing Diffuser.

That’s all!!

As far as tools you will need:

- An exhaust pipe cutter that will do 3.5” pipes.

- An exhaust pipe expander because the tips and muffler come with tight clearances which you need to spend slightly apart to fit over the male connection to then strap down.

- An Exhaust hanger removal tool for easy removal of old muffler (optional as you can make do without)

- A De Burring tool to clean up cut pipe.

- A 1/4 drill but to open up an existing whole to fasten Dummy Flap Actuator.

Of course you’ll need a ratchet and sockets to remove and install but that’s the easy part I’ll leave it up to you.

Good luck and I hope this helps out anyone who is in my shoes looking around for accurate information all in one place 👍🏼🤙🏼

Id image those chrome tips would not fit on a 2021 G30? I'm looking to get the M Performance exhaust but it looks like they discontinued the chrome tips for my model (Part #18302444529)
