Hey guys,MY 8 is a 2004 with 90K on it, Im in need of a new catalytic converter, it was changed by the dealer along with the engine about 2 & 1/2 years ago, about 20K put on it. So is there some type of factory warranty on it other than the 1 year parts & labor the dealer is telling me. the other question is that is there an aftermarket CAT that i can buy thats legal in NY. Really appreciate the help. Thanks
