Finally some warm weather this weekend to install the diffuser.
Removing the stock one wasn't bad. First had to remove the stock tips with a large Torx bit. Then remove a couple of screws. The only hard part was removing two rivots on each side but I ended up just snipping it off with pliers.
Two parts of the OEM bumper which hold the stock diffuser had to be cut off with a saw but I assume it'd be the case for any new diffuser.
The diffuser I got didn't have predrilled screw holes but there was an indent in the plastic where it should be. So after I found the size of what is supposed to go through it, I drilled the holes and they aligned pretty well.
The fitment of the diffuser was pretty good. All the tabs lined up well. The width seemed a teeny tiny bit short but gave for a tight fit. Can't see it coming off for any reason.
Pretty happy with it as of now. The Magnaflow mufflers come in tomorrow and I hope to get to the muffler shop this Thursday to install the muffler and tips.

I didn't go carbon fiber cause nothing else on my car was carbon fiber and I don't plan on adding anything else with carbon fiber either. My car has more of a black and chrome trim theme going.

Looks good! Can't wait to see the finished product with quad tips!

Probably should have done that before installing it lol. I kind of like the different finish since diffusers on a lot of cars don't match the body. Can always paint it in the future. Wouldn't be too hard to take off to paint. Will probably leave it for now though.

Thanks for the positive responses, guys. It's such an improvement from stock. It might be more mental with the sound but I feel the car pulls a little harder with more exit flow from the Magnaflow mufflers. Maybe a little bit of both. But Magnaflow does claim about a 10% HP increase so I'll take it.
Took some more pics yesterday after work.

I'll put them here for anyone else interested. Note that the diffuser is matte black and not carbon fiber. There are other ones for carbon fiber.

I'll just write it here for others to see.
First you'll remove the exhaust tips connected to the bumper. Then you remove the OEM diffuser. Then you'll cut off the 2 flaps the held your old diffuser. I used a handheld jigsaw. Careful not to scratch the bumper above. Tape off if you'd like.
Then attach the new diffuser using the same tabs. There will be two bolts underneath that you will attach the new diffuser to. You will have to drill your own holes if there aren't any there already. I used the same plastic nuts already on there but upside down. The sides will need to be attached with smaller screws. That should be the extent of it.
