can I have the cake and eat it too?

YouTube - 370Z w/ Full Intake & Exhaust Mods

Hmm, given that, that set up might be too loud for me

Hmm...

That's funny. I wish my car was louder. Both my previous cars were louder so that's what I'm used to!

Lol. It's not that loud. It's his microphone. The exahust is no lounder than the turn signals. clunk, clunk, clunk, clunk, clunk, clunk.

No need to be so self-deprecating. If you want a car that doesn't drone as much, that's perfectly fine. Try to get what you want, and maybe you'll get it (and maybe not!). I really hate it when someone has a problem and the response they get is "you should have bought a [Volvo/Prius]", or "learn to live with it".

Sounds like you chose the right course. As mentioned, "drone" is where the exhaust frequency matches the resonant frequency of a panel in the cabin. The fix is to reduce exhaust sound, change the frequency of the exhaust, or change the frequency of the panel which is resonating.

I would start with the hatch floor, and work your way forward until it's resolved. Focus on the middle areas which are directly above the exhaust. Sound deadening isn't that heavy (~.5 lbs per sq ft.), so as long as you aren't a weight freak I don't consider that a huge concern. GL.
