"Brand new in the box 2007 g35 sedan exhaust made by stillen.
Asking $1,100.00"

Stillen does not even list an 07' exhaust on their web site. Hmmmm

There are users here who have it installed already, pics etc etc

You would probably need to search in the exhaust sections to find em, I am sure they have been moved there.

here is the link-
