The Stovebolt Site Forums The Shop Area Engine Shop what size exhaust pipe should I use

Ahhhhh yes, Timothy you da man. Never really took notice of
that section, but it clearly shows and describes the
construction of that muffler. The one on my '54 was as I
suspected, and aftermarket exhaust system, the muffler looks
right but the flanges are staggered like the one in Paul's
photo.
The NOS part that Paul has doesn't appear to have rounded ends
as does the muffler in illustration #3 of your second link.
However, in illustration #4 the ends appear flat. Just one
more thing for us to wonder about, probably used an older
drawing for #3 as I seem to remember seeing those domed ends
on some mufflers back in the late 50's when I worked in the
business.
In your last link, to the 1948-51 manual, they carried over the
exact same earlier illustrations.

Thanks for the reminder, i.e., if all else fails,,,,read the instructions.
And you should know me by now Tim, tain't being snooty, not a
snooty bone in me body. I'm just pokin' a bit of fun at ya, I
knew you'd come up with an answer if I rattled you cage, cuz
I know your attention to detail.
