could be fumes inside the exhaust pipes, my SS smells kinda like that after i drive it and when i shut it down i exit through the garage door and you can see smoke slowly creeping out my 5" tips & up into the air when its cold outside.
the smell is possibly from the cats when they burn the unspent fuel that leaves the engine. i've talked to tuners and almost always the camaros and vettes run rich (around 12:1 a/f ratio) at WOT from the factory (ideal is 12.5:1 to 13:1 a/f ratio), so they probably have a lil extra fuel not being burned inside the engine than most vehicles.
but don't take my word for it, take it in and have a certified mechanic diagnose it under warranty.
