The hope is that I will eventually get my Thunderbird Sport up and running. The aftermarket Emgo Reverse Cone slip ons are terribly loud. Any suggestions for packing?

I had good luck with the Moose Racing repack cartridge:

Toned an FMF down nicely.

I purchased some of that uber hi temp insulation for kilns. Has held up for over 13 years on my ducati. got a big ole box of it for not much $$$$

Where do you buy the kiln hi temp packing?

was long time ago, just google it. It's a batt type material and I had to wrap with stainless screen to keep it compacted around the core when I put the muffler back together. but that stuff just doesn't seem to wear out.

Having the same mufflers, I understand your concern. Motorcycle baffler wrap was difficult to work with and did not last long. I went to the auto parts store and bought a sheet of Bondo fiberglass body repair fabric...it was easy to use and has held up for over 6 months significantly reducing the noise. It was cheaper than the motorcycle baffler wrap.

that looks like what I used all right. got the highest temp stuff I could. Wear gloves and mask when messing with it, just to be safe.

I maintain more than one repackable muffler on various bikes.
Many factors are relevant when choosing a repacking material.
If the material is too dense or packed too tightly, it will not as effectively deaden the noise. If the material is too loose by nature of the material or the packing force, it will burn out too quickly.
Some old-timers like to use stainless steel wool.
I favor the string-type muffler packing as already shown on links such as Moose Racing etc. The standard fiberglass mat type material has not lasted as long for me.
Kiln insulation is usually a very dense, ceramic-based material. I'm sure it would last long and it may absorb the noise adequately for some riders but I am satisfied with the high-performance version of muffler packing. We are not talking huge dollars here.

I've used this for years and lasts a long time.

Lots of good suggestions here and very interested in this one. When I checked the site to buy, however, it offered me choices of some bikes but muffler choices per se (like "for Emgo Reverse Cones"). Stupid question, but how do you know which cartridge to buy?

I don't know that I'd go that route. Those are preformed inserts that you slide in over the inner tube of the muffler. If not close to the size/shape of the stock muffler, looks like you would have voids.
Some of the exhaust manufacturers, e.g. Akrapovic etc, use these systems since they are already formed to fit inside their mufflers. Those, however are expensive.
The string-type packing from Moose and others normally work well and last reasonably well if properly installed.

Sorry for the slow reply, bp. I'm fairly certain I ordered from Dennis Kirk, I think I typed Moose Repack Cartridge in their search bar and then chose by length.
