So I am about to buy a catted MAC H-pipe and was wondering if it should bolt right up to my am thunder catback. I'm pretty sure it will but mac says it will bolt up to stock or mac catbacks. But I guess since the american thunder is almost identical to stock it should be fine.
I'm thinking that if the Catback will bolt up to a stock h-pipe, and the mac h-pipe will bolt up to the stock catback, then the catback and the mac h-pipe will bolt together without problem. I mixed and matched my exhaust system with Hooker headers, a BBK x-pipe and flowmaster catback, and they bolted together fine.
