Did you notice it doesn't have any clips on the topside? (of course you did) I don't want to rush this. I want to take some time to remove the rear bumper, carefully remove the NPP diffuser, and then attempt the install... this in case I need to reinstall the NPP for whatever reason.

I was thinking some 3m double sided tape for the topside, and screws, bolts, or rivets for the underside (depending on clearance).

I'd love to see pics if you can accommodate... wondering what areas don't look right. Thanks for the feedback.

Yeah I really don’t know why they didn’t put clips on the top but they did on the sides. I used 3m double sided tape on the top but it doesn’t want to stick very well because the bumper has more of a curve than the plastic diffuser, so the diffuser wants to pull away from the bumper. I ended up using one self tapping screw towards the outside of the very top of the diffuser (which I hate to do) in order to hold it on but I’m not sure how strong that will hold on. I used all 6 of the stock mounting points on the underside and that seems pretty strong. I’ll take some pictures for you soon but basically the diffuser looks like it was made from a mold, and the mold may have shrunk or something. So the diffuser has like easily a half inch gap on each side, and on the far left, the diffuser is sticking out about three quarters of an inch or so from the bumper. I know that last part doesn’t make a ton of sense but once you see the picture you’ll see what I mean
