Chuck, there might, and probably are, some effective sound dampening sheet material that might hold up to the heat without danger of degradation, but off hand, I don't know what they are. Thicker is always more effective than thinner in sound dampening. The JM and OC 2" panels are great and give a lot more sound insulation than anything else I can think of that is 2" or less in thickness. Dynamat might have some firewall insulation that might hold up to the heat being thrown off by the RPI resonators, but it won't be as effective. If the mufflers break in and tone down as several posters have indicated, then, I'm looking forward to the combined decrease in
cockpit noise that I'll be experiencing.
