I am in the process of redoing my seats. looking to have the seats re done. Also was considering if the price is right having the carpeting replaced, with that came the thought of possibly noise dampening as well.

Has anyone done that? if so what was the cost, and was it effective?

thanks

 

I'm in the process of adding sound dampening to my '02. I went with the VetteNuts pre-cut kit because it's lightweight. Also adding a layer of Ensolite. So far I've completed the rear of the car and haven't really noticed a difference. But I added a layer of Ensolite to my trunk partition and that did help cut down on the exhaust noise.

I thought that buying the Ensolite separately would save money over the pre-cut option, but I wound up having to buy more and ultimately spent the same money while also wasting a huge amount of time cutting it to match the pre-cut pieces from the VetteNuts kit. It took me a day to do the rear of the car, and 60% of the time was spent cutting Ensolite. I can't imagine trying to do this without a pre-cut kit as a template. That would take me forever because I'm really detail oriented.

 

If done right, it's very effective. I did mine while in the process of upgrading my stereo system. Since I had the seats and all the carpet out, I bought a few boxes of Dynamat Extreme.

Yes, it is a time-consuming process and yes it is a pain in the butt, however, if you do it right, you cut down on road noise, as well as deflect some of the heat that comes up through the floor. At least it did on mine because the material is foil-backed.

Pay particular attention to the doors. That's where I noticed the biggest difference. There are several write-ups with photos in the Audio/Electronics section. It was a worthwhile investment for me. I did it myself so over the course of a weekend, I got most of it done. Once it was complete, I found squeaks in the halo trim so I did that as well.

Good luck!

 

I did the frost king mod once, but I didn't do the doors. Not a huge difference in noise, but the temp reduction was nice. The tunnel used to burn my leg, and now it is much cooler

I did dampening on the doors - used 2 small sheets on each door and then a high-frequency wrap on the entire door. I didn't do anything to the floor. The trunk I did 2-3 layers and then the high-frequency wrap.

Results: The drone from the exhaust on the highway is not as bad. Road noise has reduced very slightly overall but still somewhat noticeable. I paid $170 for everything and only added 27lbs to the vehicle.

The aftermarket audio I put into the car now sounds much better as the rattles have been taken care of. The wrap also helps keep the sound in the car.

I'm sure if I spent another $100 I could do the floor, pillars, etc to reduce the sound even more, but I'm lazy like that to tear out the seats and carpet.

I'd recommend to focus on the trunk and doors. Just those two areas alone will improve. If you are doing the seats and carpet, then definitely go ahead and do the floor while you are at it!

 

i can talk in mine even with the LT and exhaust. My 16 year old Aussie is at piece since it was done. Did the Sound and insulation at the same time.

 

I did the Frost King on my tunnel as well and was very happy with the reduction in console/tunnel temps.

 

I went down your path last summer. I researched this issue at length and saved (electronically) the threads/websites that I found most helpful/informative.

First, you should decide what "problem(s)" you are attempting to resolve. There are three interrelated issues at play: temperature abatement, vibration dampening, and true sound deadening. The remedy for each is a bit different from the others, so decide for yourself whether you truly want only to address sound deadening, or whether you really want to address all three. I addressed all of these issues because I didn't want to tear apart my interior a second time to address any issues I neglected to tackle the first time.

Here are useful threads posted by

1. A thread by Mike Mercury who is upgrading his C5 (pay attention here; Mike REALY knows his stuff): http://www.tim-yvonne.com/mikemercury/sound.htm

2. A thread by Forum member Thrash. Although he is working on a C6, he addresses the sound deadening issue (which is equally applicable to our C5s) in great detail. Scroll down that thread to his post #9, and focus on his comments in paragraph 19 entitled "DEADENING, LAYER 1 – STIFFENERS, BUTYL & BXTII." Here is the thread:

3. In Thrash's discussion above, he mentions one vendor who you should call because he has directly responsive products and in-depth knowledge. This vendor is Sound Deadener Showdown, and his website is: http://www.sounddeadenershowdown.com/
Read his website discussion before you jump into anything, as it is very informative.
His products seem to be very cost-effective, and he will give you personal attention, talking in as much detail as you wish regarding your objectives and how to achieve them.

I did the Frost King all over the interior. It made a HUGE improvement. If your going to take the seats out, you should consider the tunnel and tub area also. It really was amazing. It may take a little extra time but its the Winter-GO FOR IT ALL !!
