can I have the cake and eat it too?

I've had it with the exhaust for about 2 months now. I have decided that I am going to install some sound deadening matting in the trunk to take the edge off. Thanks again all!

i wish the set up was louder

^Ditto. One of my favorite past-times is seeing how many car alarms I can set off as I drive by in a covered parking garage. It's harder now than in my previous cars.

I hated when people used to do that to my Trans Am. The stock alarm on it was so sensitive that if I farted in my house, the car's alarm would chirp a couple times. One time, an old lady with a walker walked by my car and it went off.

Well, maybe it wasn't that bad, but every honda with a fart can that drove by set off my alarm. Damn ricers!

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.

Excellent advice 2bit. That is what I'm planning on doing. I have purchased high quality sound deadening material and will post s results. Thanks again...
