Considering its a sports car i would rather have Nissan not install all the heavy sound detening material and get rid of some of the other added extra weight. If i wanted a superquiet coupe that makes 300 HP and has a nice interior i would have bought a Mercedes.

Dynplat the whole interior??
How do you not like the sound of your Z??Are you guys rolling in Z's with lift kits and huge off road tires or something, because I dont know this "noise" people are crying about,... then again my upgrades drown out "noisy tires", LoL!!

Well this is definitely not a fantasy thread, it's a plan of something that will happen. A $1,000 isn't that bad for adding class and refinement to any car.
I also realize that this is a sports car, but that doesn't mean it has to be loud with a lot of driving noise. Just a minor gripe I plan to fix. I will post before and after decibal levels to confirm success.

All cars are just tin cans. To make them quiet, you have to add sound deadening materials. That adds weight - something counterintuitive to a sports car.
As others have indicated, you can definitely reduce the road noise with the proper choice of tires. Of course, you sacrafice grip/handling sometimes when you go to a softer/quieter tire.

The wife drives an Mercedes SLK and while it is a few steps up from the Z, it's not really that quiet or soft riding. Like everything else involved with a car, it's all about compromises.

I happen to agree with the OP and had great success with DIY dampening. The biggest difference was in using a hoodliner for me, but I also put down a butyl rubber dampener behind the doors, under the carpeting and in the trunk. Each section was done over a few hours on a weekend so I was able to feel/hear the difference after dampening just the hood, just the doors, just the trunk, etc.
Yes I added about 45 pounds to the car but it's not even possible to feel that weight. Not even a consideration for me with the benefit of what it does to the inside of the car.
I should mention this is the third car I have done this to - and after my first car I decided it would be standard for every car I own from now on. Totally improves the interior feel, better sound from the stereo, more solid, fewer rattles and squeeks... nothing but good things to say about doing it.
The Z really is designed as a sports car and so I would expect a few luxury items to be left out. Nissan saved the luxury items for the Infiniti line - but even those benefit from aftermarket dampening.
Keep in mind there are a lot of different products out there. There are dampeners like Dynamat and BoomMat, but those are meant to be applied under an insulation layer for ambient sound reduction.
I would recommend starting with a hood liner.

On a related note, I just bought a stereo with 8 15" subwoofers and a 5000 watt amp and it's kinda loud too. Anyone have any ideas on how I could quiet her down some? 
I do like your determination though, and I'm in for pics of your DB meter before and after.

I understand the tire noise is probably the biggest offender. I was hoping for some input from members on what they have done to quiet the Z33 down.

Compromise.
Well here's the deal. You don't have to compromise. This is exactly what the aftermarket is for. To fix the shortcomings of the manufacterer.
Here a video for the rest of you. You know who you are.
And for all you haters on this forum, which is like half of you, here you go.
