As a fellow vette owner I just had to jump in and say nice car, not a bad price either. But you would come out way ahead if you put it back to stock and asked slightly less. You could recoup more money doing that and selling the mods seperately. You already have a limited market with the Mil Yellow, now add in headers and bullets
and it may not be everyone's cup of tea. Also, my car sounded very tame with headers and the stock catback. Wouldn't you expect your car to be extremely loud with essentially no mufflers? Hehe, you think its loud now wait until you install a supercharger and cam. In any event good luck. But my advice is to keep your car and just install a corsa or other quieter catback. Corsa's are awesome on the highway, barely louder than stock. But at WOT they are fairly close in volume to your bullets.
