Muffler Man Mystery in Idaho...

Who can tell us anything about this Muffler Man? Reportedly from Idaho circa 1997. Hints? Suggestions? I recently spent two hours driving around Nampa in search of an "in-accurate" Muffler Man report at the Hurricane Car Wash. It's GONE. Is this him? Although, this one looks suspiciously like the one in Wendell. Hints? Suggestions?
