Reply to "ANSA Mufflers"

I tend to agree with Dave- my cut-apart 1972 mufflers had very thick cases, no weep-holes nor rust, and no packing in either the tips nor the cases. IMHO, the only differences in OEM 1972 std mufflers and slightly later 'GTS' mufflers was, the washer-cap on each outlet pipe (present in std, absent in GTS), and a thick circular shim welded in the case intake (std), which if cut away, allows a 2" inlet pipe to be inserted with no other changes.Std was 1-3/4", GTS inlets were 2-1/4" I think, and GTS used an additional triangular sheet brace/bracket from inlet pipe to case, presumably to reinforce for the 'severe duty' such pipes would be expected to get in service. Note that these are as-received 1972 mufflers; later made units may indeed have had all kinds of other additions.
