Do they make an "Off-road" Y-pipe for a 92 Dual cat 350ci Z28? If so, were can I buy one. Thanks, Troy.

 

Nobody makes aftermarket y-pipes that bolt to the stock exhaust manifolds. They only make y-pipes that come with headers. You need to go to an exhaust shop you trust and have them make you one.

Keep in mind, removing your cats on a street car is a federal offense, punishable by a fine and/or jail time. You, and the shop, can be in trouble.
