  Most mufflers have been replaced by now, so you will only get the aftermarket sizes anyway. The following are the specs from Walkers factory replacement line.


1959-1960 all  Muffler
 number    type                     Overall   Shell  Inlet    Outlet
21158     TriFlow oval 3 1/4x 7 3/4   25 1/8    20 1/4  2       1 3/4 side in /center out

1959-1960 all except 75 ,CC Resonator
21159     Direct Flow    5 1/8      27 1/8    22 1/2  1  3/4   1 3/4 

1959-1960  75,CC resonator
21104     Tri Flow  oval 4 x 7 3/4  20 3/4     16 1/2   1 3/4    1 3/4 side in/center out

By direct flow,I think they mean round ,with the pipes in the center of each end.

Seconding using Waldron's. Their parts are very well made and highly recommended. I used them to replace the entire system on my '59. That can be seen here:

Plenty of pictures there so you can see what they look like. They sound great too. The inlets are 2" and the outlets are 1 1/2". The pipe from the manifold to the muffler is 2" and the rest from the muffler back is 1 1/2".

I put Waldron stainless steel on my 60. Sounds great,(original) fit correctly and competative price.

As the PO is in Russia, ordering an exhaust by Waldron may be problematic...

Thank everyone!   I bought "AP Exhaust MSL Maximum Mufflers 6521"

No problem, but  parcel takes a long time.  Only problems with payment
