I am not a exhaust expert but the Thursh Turbo mufflers where around in a the 70's. I don't think they could be knock off because Flowmaster did even exist back then.

Is this a magnaflow that is a stock replacement? The muffler that comes with magnaflows Cat back will NOT fit a stock exhaust. The inlet and oulets are in different places.
