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.
