Well, it actually took me about 5-6 hours, but the end result is very nice. I installed a set of new old-stock Road King mufflers on my 98 RSTC2. The hardest part was making my brackets, but I got to use my new wire-feed welder, Ye-ha. Sound is much better than the drilled out stock mufflers. BTW, I didn't drill them out, they were already that way when I bought the bike. They sounded terrible. Getting the new mufflers to slide over the exhaust pipe was a real pain, with lots of grinding and filing, but finally got it.
Thanks to all for the information and pics.
