I don't follow?? Catback exhaust? If you ordered a 2ss it has true dual from the headers? What are you talking about? What exactly do you think you're getting in that option? I believe it is exclusively for the V6.
I alos order mine yesterday - order book actually took the order in the system; no need to wait until tomorrow.
I'm first and the dealer is great and has 11 more allocations through Q3. COUNTRY Chevrolet, Warrenton, VA.
