Ken,
The resonator is nothing more than a glass-pack muffler. On the
late-style version with the megaphone tip, it is straight through with very
little reduction in pipe internal diameter and no baffles. Also, the
later-style exhaust places the muffler behind the driver's seat, instead of
within the "X" of the crossmember, which was directly under the seat. A
straight pipe replaces the muffler.
You can use basically any
straight-through glass-pack you want as a resonator, as long as you match the
pipe diameter to minimize installation problems. There are varieties with
chrome tips which look nice. I am not sure what I have on my '67-1/2, but it
isn't stock. Your local speed shop (probably not Midas, etc.) should be able
to install (or sell you) something appropriate.

Subject: Re: [Roadsters] 1600 exhaust questions
I'm not sure what the
resonator is, or what it does. That's the primary reason for asking all
ya'll. :-)
I had the original exhaust manifold replaced with the coated
header, and they installed a flex pipe at that time as well, but the rest of
the exhaust appears to be factory "fresh". So as memory serves, there is a
pipe running to a muffler near the area of the drivers seat, to a pipe over
the rear axle to the resonator and the fancy flared exhaust tip.
Eddie, do you
recall a specific muffler you used? Should I just go shopping for a new
muffler with the approximate dimensions of the resonator?
I should probably
just drive it over to my fav exhaust shop and ask them? Huh?

I
should be stealing Tim's signature, but not sure how well I'm learning...
