Hi, Merlin, and list(s), the morganowners reply shown for context, and some of what I've found non-specific to my task shown for others who may have a use for it,

Found this: MAX-GAIN SYSTEMS, INC. : Fiberglass Price List
1 1/2 tube is only 1/8 thick, but I'd think you're going to glass it in anyway and would increase the thickness by doing so? Or go with a 1 1/4 and build it up to 1 1/2?
$12 for 4 feet.
Cool site. 1/8" wall is ample for the application...
I'm actually needing a 2" OD but the PVC I used for a kludge to bypass the muffler
is 1.5"ID/~2"OD - and their 6" sample pack (leaving me with lots of smaller samples) is only 9.50 (vs a 4' section, which leaves me with lots I doubt I'll use in my lifetime, at $26). If I needed *really* stout pipe, they also make a 1/4" wall pipe (standard being 1/8") in longer lengths. However, feeling around in the remainder of the spigot on the muffler
suggests that the original wasn't 1/16" thick, even, so I expect that will be ample.
They're apparently a comms/electronics/HAM site, as there's lots of electronics/HAM-sounding stuff there - and a ham friend of mine tells me that it's not heat-rated stuff, so I'll have to keep looking...
Another source I uncovered is MARINE WET EXHAUST SYSTEMS
, where a 4" section is $8. That will accomplish what I need, but shipping
(haven't explored policy on either yet) might make the sample pack above cheaper, and have just that much more (don't know the merits/problems of using slightly longer and having it stick further into the muffler) length. Given that it's Trident, there's an outside possibility that I could get it through Port Supply when I order the other stuff I need. Update from when I started, they do have it, and offer a whopping 0.50 discount from Mesa's price
Then, there's McMaster-Carr
- having ordered odd stuff from there before, I'm surprised I didn't think of them - but they only sell 5' lengths, and it's food-grade stuff, not exhaust
hose, so, with an operating range of -50/+140F and a max temp of only 200F, that might not be a good place for it. OT, they sell telflon strip which is great for sliders, which is one of the apps I used them for, and it's also where I got the parts
for my fuel
Yet another correspondent turned me on to vernatube 1100 series pipe. Here's one source: Centek Vernatube 1100 Series Premium High Temperature Fiberglass Marine Wet Exhaust Tube - 2 inch OD - Engine Parts and Supplies - Exhaust Risers, Elbows, Fittings and Headers - Centek Vernatube 1100 Series Premium High Temperature Fiberglass Marine
which has a large selection of diameters, not just the 2" shown in the URL.
I've also done a bunch of searching, and have reasonably conclusively determined that what we have currently is a Vernalift muffler, PN 1500027, based on the specs and pix seen here: http://www.boatfix.com/catalog09/614.pdf
. It's available in various places from 121 (Port Supply, cheapest I've found so far) to close to 200 at various other vendors. Currently debating whether to replace it, or fabricate the new intake. I'll make that decision when I pull it out (which I'd want to do anyway, to do the work more conveniently).
Thanks to all who suggested sources...

"Believe me, my young friend, there is *nothing*-absolutely nothing-half so
much worth doing as simply messing, messing-about-in-boats; messing about in
boats-or *with* boats.
In or out of 'em, it doesn't matter. Nothing seems really to matter, that's
the charm of it.
Whether you get away, or whether you don't; whether you arrive at your

anywhere at all, you're always busy, and you never do anything in
particular; and when you've done it there's always something else to do, and
you can do it if you like, but you'd much better not."
