I have it as well. It looks just as aggressive as "necessary", it's very good quality, especially considering its price point, fitment is 99% perfect, and workmanship on mine was impeccable. It might even be functional, but let's be honest, that's not why we buy an SS diffuser.

Diffuser installation is not trivial in general; while some youtube videos would have you think you can do it without removing the rear bumper, don't believe that for a second, unless you want to mangle your bumper. Just bite the bullet and pop it off, devote some time to this project.

Yep that's it. It's definitely more involved than I anticipated, removing the bumper is absolutely necessary.
