This is a 2-piece shroud cover for your 2005-2006 GTO.  This is laser cut from mirror polished, 18GA stainless steel.

These 2 pieces adhere with 3M double-sided automotive emblem tape.

NOTE: These pieces will ship with a protective film to prevent scratching during shipping.  when you remove the film, you may need to clean up the edges of the pieces with mineral spirits.  This will remove any adhesive left from the film - this is a very little amount and can be done in about 5 minutes.
