Supercup muffler inserts
I went with Car Chemistry inserts because Ken was so helpful. Supertrap is another choice, but I had a hard time sorting out what might fit.
Perfect size for supercups is the 3.5" 2 disc insert. Price @ $125 for the pair.
These have done a nice job taking the edge off the supercups. If you're looking to cut the noise juuuust a bit and be less of an obvious noise violation target, these are da bomb.
Right now I just have them tacked in with a zip tie via the 2 holes in the end of the Supercups - the inner disc lines up perfectly for retention via those holes. A better and easily reversible solution will be to tap the 2 holes to allow the use of threaded machine bolts. Maybe next week

Mark,
I just took the car for a spin, and let's just say it's gone from obnoxious to loud but reasonable. I'm pleasantly surprised. If I get some time later this week, I'll take some drive by video both with & without the inserts.

Still happy with the inserts. I need to order something. My 1995 has catbypass and supercups (it's a track only car) and I got compliants at the track from guys in my run group on how loud it is. I went with supercups for a weight reduction, but without something to mediate the sound they won't stay.
On another note where did you get the carbon fiber stuff???
