Carbon Fiber Rear Diffuser - DIY?

I just received a new CF rear diffuser. I was searching the forum to determine if this is a DIY job (could not find anything helpful) or am I better off going to a local shop to have it done. I know there are 4 plastic rivets that hold in in place. What is the best way to remove the old rivets?. It seems simple enough, but I will defer to the guys who have already done it.

The best way to remove the plastic rivets is by snipping them from above.
Once those are out, there is still quite a bit of tugging and cursing to get the plastic clips (part of the diffuser) to detach from the corresponding slots in the bumper. Eventually the diffuser will cede and you will be victor.

Dkat, I also found there was a lack of good diy on this... Hopefully all goes well for you!

Thanks again for the Roundel also!

The diffuser will still be very firmly secured even after you remove the rivets, so don’t freak out if/when that happens.

Decided to change rear diffuser as Presidents Day project. Is a rear diffuser a DIY project? Answer, yes & no. I had a tough time getting the existing diffuser of . A real PITA. I ended up going to a friend house to install the new CF one as you really need another set of hands. If that friend has a lift, even better!
With another set of hands, Install was 10 minutes. It came out very good. Fit & finish perfect. It is better than that slab of gray plastic IMHO.

Is that an OEM CF Diffuser?

If so, what is the BMW part number?

Thx!

No, Not OEM CF diffuser. BMW should have made this, They would have sold a bunch of them. This is a Revozport OEM style CF rear diffuser. I liked it because it did not look like an aftermarket part. Subtle enhancement of the rear. My car had the BMW CF rear spoiler & mirror caps installed by the previous owner. Weave matches perfectly. So, it completes the look.
It was overcast when I took the picture. Looks more pronounced in the sun.
I purchased on a Black Friday sale & saved a bunch. If considering, wait for a sale.
