So I just got my nismo diffuser for my 06 g35 but I'm not sure how to install it...since the stock diffuser it has looks like its together with the bumper and I can't take it off... Or maybe I'm just dumb... Anyone mind explaining how to install it...thank you

 

Do you have the stock bumper or an aftermarket one? If stock then the rear part doesn't come off, the diffuser just goes over it. Post pictures if your unsure of what bumper you have.

 

Yep stock 06 bumper and yeah I figured out it just goes over it, guess ima drill some holes in it and use 3mm tape

 

That's the exact way I mounted mine. Its not 100% perfect but it'll do. I actually did away with the 3M tape, after a while it started to slowly unstick from the bumper.

 

I got mine from outcast garage and they told me the figment should be 9/10 so I'll find out tomorrow if it fits

 

There stuff is spot on. Forgot where i got mines from, but its like a 7/10. Post pics when you get it on man , might persuade me to get one of there's if it fits better.

 

If it fits properly you shouldn't have to drill too many holes. The tape works well. My diffuser didn't fit all that great so after a couple weeks, the edges were not flush.
