'79s are non-catalyst cars from the factory...
My car sounds kind of raspy compared to other 930s. I don't really know why. It sounded raspy with the original USA exhaust and still sounds raspy with the upgraded system (SSIs and rarlyl8 muffler). The only thing I can think of is that the primaries are smallish (both on the original set up and SSIs) compared to others I've seen.
