When you say loud do you mean in the cabin ?

Yes in the cabin - outside is great.

lol i don't have mine yet, but after owning the Z w/ just HFCs for a while i'm gonna have to agree. Then again i literally go to the range just to smell gunpowder and hear sh#t go bang.

You need to sound dampen your car.

I have a one inch thick foam mat in my hatch area and haven't noticed much of an improvement. Do you recommend any stick on products?

Dynomat or and second skin or even the stuff from lowes or home depot that works great

I was thinking of going with motordyne over fast intentions because from what I heard about fast intentions being to quiet, vs motordyne was loud. But now im not sure? I've never heard either one in person just on videos, Is it really that loud? I wanted the fast Intentions non resonated version.

That is it. Start with the trunk and if that does not help, do the floors and doors.

Personally I like to hear all the noises of the road and the car. Gives me that connected feel. If I wanted a quite ride, I would have bought a sedan of some kind (never, never, never..........).

I've heard that a foam layer is necessary to dramatically reduce noise. I've used the stuff from lowes (peel and seal IIRC) and it worked great for dampening the trunk with subwoofers.

Yes peel and seal works just clean any area where you are going to apply.

I have dynamat in my trunk but this reduced exhaust volume in cabin just a little but noise from road/tires has almost completely gone.

Hi Cegla. Pardon my ignorance, but what is dynamat and where can it be purchased?
Thanks.
