Several days ago, I swapped out the Hooker AeroChamber mufflers with a pair of Dynomax Super Turbo mufflers. While it did quiet it down some, I discovered some major exhaust leaks where the primary header pipes slip into the collectors. This coming week, I'm going to seal up these leaks with Permatex 80335 Muffler & Tailpipe Sealer. Sealing up these leaks will help to further quiet down the exhaust system.

I took it out for another drive today. I recently had some coolant leak out of the radiator overflow nipple on several occasions. I tried a higher pressure radiator cap, and that seems to have solved the problem.
