DynoMatt ? Did it work for you ?
 

Wanted to get eveyones opionion on using DynoMatt to reduce the crazy loud road noise ?

is that like a butt dyno pad?

.. or you mean dynamat? :ugh:

+50 horsepower on the dyno?

It helps. It can help a lot depending on what type of sound deadening mat you use. Dynamat is one of the more expensive choices. The tar based types stink, so you need to pick wisely.

you mean pick wisely... :icon08:

I did from the shock towers back with GTMat and it did a good job of quieting things down.

yah, i used dynamat. it made a noticeable difference, but my muffler is pretty loud so it's not like a lux car by any means. :D

Lmao give me a break im from New Orleans where the public education system sucks lmao

Yes Dynamat lol

Thank you guys ! Making an appointment next week to get windows tinted and while there I'll have the Dynamat installed as well.. The road noise is just crazy loud and bothering the **** out of me lol.. And is it me or did the change the exhaust from the 350z to 370z? I always wanted a z/g35 bc of the factory exhaust sound and seems my 370z does not have the same tone ?

The rear of the car has almost zero insulation from road noise. Take off the panels and line it there as well.


About the exhaust, do you want it louder? If so, go aftermarket, fi,ark ect


Road noise doesn't bother me..im used to it.. expected it in a tiny 2 seat sports car for mid 20s. Nothing that a aftermarket exhaust and decent audio setup cant fix too.

Until I got headers, HFCs, and a CBE, I thought the 370Z was too quite exhaust-wise. What got me was the road noise and what drove me nuts was sand etc pinging off the rear wheel well. I covered those suckers and it made a world of difference.

You can go nuts and do every square inch, but I think it is a waste of money (diminishing returns). Get the large sections of sheet metal in the doors, trunk, wheel wells, and maybe the floorboard and that will make all the difference in the world.

Or go nuts.

I will be saving this thread for next week to share you guys advice and see what they recommend and make the decision..

As far as exhaust I deff do not want loud.. I personally love the old sound of the 350z/ and g35 lol I dunno maybe I'm just crazy but it just does not seem as loud as the old ones use to sound.. Headers hmmm maybe the cheaper way to go to get better sound and still keep it somewhat quite -

I just did a stereo upgrade, I did the area behind the seats in dynamat extreme, and also did 1/4" dynaliner. Where as before I had to turn my volume up to around 20 for a comfortable sound level that has now dropped to around 14-15 after doing the dynamat.

GL with the install.

yah, the 370Z's muffler is too quiet. should swap it out.

one of the many reasons why i still have my G35C with stock exhaust. :D lots of mods on my car, but the exhaust is one thing nissan got it perfect on the G. :tup:

How can i replicate that amazing sound on my 13 z? quite but so mean with a hint of luxury by far the best sounding exhaust Besides high $ exotics IMO!! I just don't want some crazy loud exhaust lol

Maybe listen to some vids/irl on how the nismo exhaust sounds? mightbe an option for you.

Oh look, a thread I could have helped in. :rolleyes:

Good luck op. ~24sqft strategically placed in the hatch area should help immensely. If you go with gtmat (Onyx or Quadro only!), tell them Tracie sent you.

After listening to some videos for a hour I think I'm sold on the ARK exhaust... Just not sure what model/type is the quietest... That **** sounds killer man but not like look at me loud sounding lol so far that is the one... However 2nd place is going to nismo as of now.. I will probably be up all night now watching videos lol thanks

And the prices shocked the hell out of me ! Crazy $$

When I was looking for my exhaust I watched so many vids, multiple times, going back and forth as to my final choice. Good luck with your search.

2 AM and still watching exhaust videos lol what's crazy even my wife loves the sound of the ARK grip v2- she normally hates all that stuff and tells me it's waist of money lol but I showed her a Video vs stock and her reponse was that's how a sports car should sound like!! I was amazed so i guess she won't be upset at me in two weeks when she sees a nice charge on credit card lmao


So decision made ARK Grip v2 - wife staMped approval :)

Ps - I'm gonna be pretty dissaspointed in about 6 hours when I go to work and start the Z up after watching these videos lol

:driving: I like the sound of the ARK also, good choice.

Can't... :( but you can make your Z sound very good. :D

Mspint+1 lol! :rofl2:

I just don't understand why nissan would screw with something that is so great!! FAIL!!

Dynamatted my entire hatch from seats back and it is a noticeable improvement. Dynamat the doors as well, it helps some with the noise, but makes the stock stereo sound so much better.

And a definite :tup: on adding an exhaust.

Not trying to dis-respect or belittle OP but comon man. Have you driven a Mazdaspeed lately? Its louder with road noise than this. I used to own one before the Z and this is like a Lexus compared to that.

It has been said before, should have gone with an Infinity.

I cleaned out my rear wheel wells really good and applied Spraydead in them then a rubberized spray over that after it dried. It helped just a little with road noise but mostly stopped the loud dings coming from the wheel wells from dirt and debris on the road... plus it makes the wheel wells look much more complete and not half assed like they come from the factory. Not sure if it will last well but it's holding up just fine with about a month in of driving. I haven't done anything on the inside but planning on doing something in the rear hatch area later when I feel like it. Will probably go with dynamat for that. Not in a big hurry for it though.

Correct me if I am wrong, but does not a sports car supposed to be somewhat loud? People who complain about the noise should have considered a Prius. They are quiet, I suppose.

Did you happen to buy that from an eBay seller named deimos_deals? Not that it matters but Spraydead is crap if used alone, but I see you used the rubberized spray after.

I think it is supposed to be about performance first and foremost, not explicitly loudness; else we would all be running around on modded trombones.

If I want noise I can go windows down; also the only place I'm allowed to listen to music uninterrupted and at a tactile volume is in the car so I like a reasoned amount of sound dampening.

Exactly how I look at it too.

i am a fan of good full sound, but not a fan of noise...

:iagree:

The grounds for divorce I used with my second wife was "I like good full sound, but not noise".

It worked.

Check your tires for camber wear. I just put a set of new tires on mine and it made a world of difference with road noise.

I used some spray on from boom in the doors and it did an amazing job of taking the vibration rattle out of it when I jam. I have Dyno in the back and it's still luad as hell with 305s. Hell, I don't care, I just crank up the Focals and I don't mind a bit. :)

:rofl2:

I got the car back from the shop. I am happy with it. It certainly reduced road noice and heat coming up from the pavement. There are far fewer rattles. The hatch can still rattle with hard bass hits. The 2 JL W3s can produce some bass in that car too. It was pricey. I am not sure it would be a good value to most. But I am ok with it since the noises drive me nuts.

I am really happy with the shop's work. Very clean install. (Sound Xpression in Mesa, AZ)

I just finished up a GTMat install of the entire trunk, rear shock towers & wheel wells, and both doors. I used their 70 mL thick rubber onyx product. Wow... what a difference in road noise. Big like night & day difference. No more rock sounds in the rear wheel wells and the stereo sounds way better. I can still hear my Berk exhaust just fine too. One of the best mods I've done. A lot more refined.

I did the same last year and was pleased with the difference. I used RAAMmat and topped everything with Ensolite foam. I ordered too much RAAMmat so I doubled up on the hatch floor and shock towers. Probably overkill but I figured I'd use up what I bought. The car sounds more solid now.
