I understand what you mean by the cowbell shape and I finally found the thread that had the inlet and outlet size specs of the sst 60 tuner barried in fast freds mod 50 secrets page 76

inlet on exhaust base plate 1 1/2" x 1 3/4" outlet 2 3/8" x 2 3/8" what over all length works best in a long shaft mid is what I'm trying to figure out now. I've got a tig welder so welding up my own tuner isn't an issue trying to come up with ball park specs for when I finally get to tearing into my spare engine.
