The 46-50 356 engine used the same part number exhaust piece from engine to muffler so with having a 47 I know that to be 2 1/4". Not sure what the smaller engines used in that stretch but I'd bet it would be around 2".

The factory mufflers show two outlet sizes -- 1 3/4" and 2". My 356 engine has a 2" tailpipe so I'd bet the 1 3/4" is the factory size for the smaller engines.

I believe there was mention on another forum about using a straight thru muffler. Thanks to a previous owner, mine is definitely straight thru but most assuredly not original. Back in my younger days, I think they called them glass paks.
