Rear Bumper "diffuser" Removal
 

Has anyone removed the rear bumper plastic piece that surrounds the exhaust tips, hides the muffler can, and has the reverse lights in it? Is it attached by clips/screws or do I have to do some cutting?

If I'm not mistaken the grey part around your exhaust is just an unpainted part of the rear bumper. If you want it off, you'll likely have to do some cutting.

Agreed with ^

i had to cut off my diffuser

Yup whole bumper

So you will need to cut if you want to install carbon diffuser?

Seibon makes one that can goes over the existing bumper

Looks just like the stock diffuser that is part of the bumper. Just covers it up.
