I'm going to check with a local muffler shop to see if they have anything any better. If not I'm going to use the Ultra Copper, for now. I will likely do the flanges this winter.

How many miles have you gotten out of the Ultra Copper? If it works good enough and long enough, I may leave it at that, but the flange would obviously be the most reliable fix.
