hey guys, i just bought a set of stock cats off a guy from this forum, but something strange, one cat has 2 bolts on it, and the other one only has one. now are these bolts extra? so i can just use the bolts from my car or are the stock cats made this way? im thinking these bolts are extra, but i need to know whether or not i need to buy bolts also when i go to the dealer to buy new gaskets. thanks
