Do i need to order both of them, my 07 S550 already has the amg package, i'm in the process of adding the S65 mufflers so i need to replace the plastic part at the bottom of the bumper beside the tips.

You need both, 11 snaps inside of 10.

The diffuser on my S550 looks like 1 piece, can anyone who has done the conversion confirm.

Here's a good representation, you will notice that the rear bumper consist of three pieces; 1. the rear apron (bumper), 2. the diffuser, and 3. the insert (middle of the diffuser in silver) which snaps into the middle of the main portion of the diffuser.

you can also take a look at this thread as well, you will see the diffuser seperate from the bumper with the inser snapped in.

Thanks for your info
I think those diffusers are a little different from the 2007 S65, i'm looking for one similar to the one in this picture

Even on the 2007, the bottom piece that's painted is apart of the diffuser. My rear bumper looks the same, but smaller than the 2010-2011.
