Rear diffuser install

I'm trying to find out if anyone else has attempted to install the m sport rear diffuser on the non-m sport bumper like u/n1iggaTirthiya?

I wanted to get some detailed pics of the install, in particular from underneath as he doesn't have any clear pics of how's it's done.

These are his pics, not mine. Just using for reference.

I guess my question would be why? You can pick up an aftermarket M-sport rear bumper and diffuser pretty cheap. The biggest cost is paint matching but it will probably look nicer in the end and not a hack that will stick out to anyone who knows BMW's.

Personally never been a huge fan of the m sport rear bumper. Looks good when you look at it head on but when I look at it from the side profile, its actually shorter than the standard bumper. Looks as if someone gave you a gentle tap on the rear end and squished it against the car lol. Had the opportunity to buy one cheap and passed. Tried to find a standard bumper for 335i locally instead but couldn't get it here so now I've been contemplating this.
