Thanks everyone, great feedback. It's nice to know that you can come to this site and get some info. quickly and easily. When I was under the car at the dealership I noticed that the header pipes coming down were stainless but is the entire piece from the exhaust port to the 3" pipe suppose to be all cast if it is original? I can't tell looking from the top part of the engine. I do have the heat covers, if thats what you call them, on the manifolds. I wonder if the previous owner went to the extent to re-cover aftermarket headers with the wrap. (I did buy the car in Calf.) I just joined the VCA Illinois region a week ago and am looking forward to becoming an expert about the car. As far as the viper tech, he did indicate that the headers and exhaust were not stock but couldn't identify the maker - so that's the reason for the questioning, otherwise I think he knows his stuff. Bringing the car to Roanoke Dodge is NOT an option. Thought the people there were very rude to me when I was looking for a car. Three months ago when I told him I was looking for a 96 GTS with less than 15k miles for 48-50k he laughed at me and my pipe dream. Well, a month later I bought a 9,400 mile car in perfect condition (ran the vin and did ALL of the homework) for 49,200. Head mechanic told me he thought that the car was in the best condition he's ever seen as far as vipers go. (maybe the 18" p-zeros and the cinsis 20's impressed him the most).
