I have only had two exhaust leaks on my 92. the first one was at the donut gasket, at the end of the y pipe. The second exhaust leak I had was at in the mufflers.

The most frequent leak would be cause by a failed donut gasket at the y-pipe/catback connection. If your engine mounts are weak or shot, it will break the gasket a lot faster because of all the engine motion.
BTW, good dyno figures for a car with a stock y-pipe. I got 196 hp on a Dynojet. I have a Perf+ y-pipe, Dynomax catbacks and an open air box.

The ATXs are equipped with a flex pipe rather than a donut gasket. Either way, that is the most likely source of the leak. You have to inspect the system to find the leak.
