There's a good little article a couple of issues back in Kit Car about replacing side pipe mufflers. I put some Stainless Specialties mufflers in my friends SPF recently. The factory ones were quite restrictive on noise and power. They made a huge difference in power with only a little more volume. It's really not a bad job especially if you get a muffler about 1/2" longer than what you have. If you look at it think about it and make up a good fixture to hold both ends in relative alignment with each other you basically just cut the old muffler out and put a new one in. There's a few threads on the SPF and other forums about it here on CC.
