I have a '98 GTS and was wondering what type of exhaust manifold it has. I know that there are two types of stock exhaust manifolds offered on the Viper. Correct me if I am wrong, but aren't the pre-98 as well as some of the 98's equipped with a cast iron manifold and some 98's and newer have stainless tubular type exhuast manifolds similar to headers? I cannot see my manifold due to the heat shield, but I would like to know if there is any way to find out which type my car has.
