I think you misunderstand how "Ask the Camaro Team" works. Not every question posted will be answered as stated in the "Ground Rules and Suggestions":

I get that some of the information presented on an Internet forum is incorrect. I have no idea if your question will be selected and presented to the Camaro team. Here is the first of a series of discussions about the 6th Gen exhaust system from one of many aftermarket exhaust vendors. This may help answer your question while you wait for a formal reply from the Camaro team.
