Whats the best sound deadening for road noise etc.

I currently dont have a convertible top anymore and have no trunk interior parts.

I plan on swapping my seats back to stock and want to install some sound deadening of some kind. I can hear a ton of road noise and exhaust etc.

I plan on quieting my exhaust down some with resonators as well.

Been there, done that. Lots of research. Happy, actually very happy with the results.

Thanks!! Wow what a write-up !

I used more B Quiet than what is really necessary for resonance killing but I wanted extra insulation both NVH and thermal. I got it!

Have any idea where to purchase the 3m stuff from ?

cosmomiller

Usually it can be found at professional shops (stereo/alarm/NVH) sometimes online. I received samples of various types (used them all) directly from 3M as a goodwill gesture in return for a write up to them. You may contact them directly especially the Honda/Acura industry rep. Felt like I was back in school doing a term paper!

How does the B-Quiet compare to Dynamat ?

cosmomiller

Both are smell free and of similar quality. B-Quiet was, at the time of my purchase, less expensive. I thought it was easy to cut and apply. Absolutely no smell at all. (Smell is a big deal for other less expensive brands)
When I got my B-Quiet it was a little thinner than the Dynamat Extreme. I could have done a double layer and still saved money but you don't need to. When you check out technical information especially relating to autos, the B-Quiet does a great job. Plus, it is easier to apply than the thicker Dynamat. Weighs less too for similar coverage. You do not need 100% coverage for it to do its job. I did in some places for thermal reasons.
