smitty
 n.— «My prefered method of quieting an engine is to use a short “turbo” type muffler just behind the engine. This is followed by a crossover pipe connecting the two banks together and then a “smitty” to bring the remaining tone down.» —“Re: Banks exaust systems” by Tencubed@webtv.net (Mike Niemela) Usenet: rec.outdoors.rv-travel Apr. 3, 1999.
