Need some advice! My car is pretty much back together. Doing the interior now. I installed Vintage Air and put Brown Bread sound deadener from the top of the firewall back. I did buy a firewall pad as well. Problem is the dash areas is together now and from some of the posts it sounds like they are a pain to do. Would you bother trying to install the jute pad on top of the Brown Bread or will it be adequate by itself? Thanks for the input, as I've never used the foil-backed sound deadeners before.

I'm about where you are with my interior project... getting ready to put down sound deadener. I planned on just leaving off the jute pad and using the foil-backed sound deadener by itself.

The only glich that you may run into by leaving the firewall pad out is that the carpet does not go high enough to cover the visible portion of your sound deadener. The pad has a flat black surface that reduces reflection under the dash and blends in with the heater box. You are going to half to install something that extends a foot up from the carpet.

Yeah, I just planned on either using some extra carpet to cover it, or if I get lazy just spray paint the foil backing! graemlins/clonk.gif

I'll be faced with the same decision once my pan replacement is complete. I thought about using a rattle can of flat black to hide the foil also.

Is the brown bread good enough alone? Looking at B-Quiet's site, some of their install pics show using the 1/2 foam stuff on top of the brown bread.

The additional insulation wouldn't hurt anything. I wouldn't paint the foil. It will flake off the first time a foot hits it. Then you will be right back where you started.

I am just doing mine right now and I am in the final stages of the interior install. The firewall pad was easy as I had everything out already and I am glad it is in as it looks quite right with the black foam there. Just gotta put the shift boot in and then comes the console and wiring. If your going to do it, do it right I say!

Thanks for all the responses! I put most of the interior together over the weekend. It looks pretty good. As far as the sound deadening goes, I think the Brown Bread is good by itself, especially with the jute backing on the carpet. Once all the final wiring is done I think I will cut anf fit a few of the larger areas of the firewall with the dash pad. You're right, the carpet doesn't go up high enough to cover the foil. The main reason I didn't put the pad in in the first place was not knowing how it would all fit with the Vintage Air.

I added the V-Comp material over the top of my Brown Bread. I used alot but it didn't go with total coverage. I used it as both a padding for the carpet and a sound dampener. Win - win.

So Rick, how did it turn out then? Is it quiet? Also did you have any clearance issues with the accelerater pedal or mounting anything else?

Hi Paul,

You may remember a recent posting on the interior noise level associated with Flowmaster products? Well, when the sound handling materials were added I had the Flowmaster Delta 40s installed. Easily the most "challenging" to interior sound management.

First was the addition of Brown Bread, I took the car out for a drive and there was an immediate drop in interior noise levels, but I have to admit, I thought it should have been more. Now, "more" is subjective but I guess with all the hype on Dynamat and such, I was just thinking Caddy-quite and I didn't get that.

Stage two was the addition of the V-Comp material. I used a lot of this stuff. I didn't go up to the top of the firewall with either product but I did go to the top of the floor pan, where the carpet ends. If I were to do it again, I would Brown Bread to the top of the firewall and V-Comp to the bottom of the firewall pad.

I used this stuff basically as jute backing for the carpet. I mounted it up to the tunnel and stopped so I could maintain a stock edge at the console. I cut out the little rectangles on the front floors to keep the carpet a little more flat. I left V-Comp out on the side of the tunnel next to the gas pedal and behind the pedal. I mounted V-Comp under the console. I put some pads on top of the seat pans. I ran it up to the edge of the sill plate covers. The back seat floor pans were done and under the seat had square pads put in, left and right. Lastly, I attached a large piece to the cardboard divider behind the rear seat to try to minimize sound coming through from the trunk in to the cabin.

With all that done, I drove it for a week and I have to say, the change in the interior noise level was minimal. I was bummed.

My new seats came in, I installed the carpet and seats and drove the car and the drop in noise level was dramatic, to say the least. The carpet did the most. I would still use all the same products but really the most bang for the buck was the carpet as far as noise reduction is concerned. I was very surprised.

Still, I had Flowmaster 40s on there and I went to the 50s. All is good now.

Sorry for the long winded post. It's tough to describe without access to a decible meter.


Rick.

Thanks Rick!!

My interior is completely gutted and I was planning on running the brown bread up the firewall and potentially all the way up to the dash (since it's all accessible now) as well as everywhere else that I could think of. The Vcomp was the unknown though. I was kind of figuring that it would enhance the affect from the brown bread.

Well, it did help but again it was minimal and I don't know what the benefit would be in a convertible.

Pictures? Let's see some. Time to update your site or one better, sell me the 69!

Noel, lets see your ride too.

Rick.

There's not much that you can do to keep noise from coming through the top, but keeping it from coming in from other areas helps. I'm just trying to make the 67 a little quieter than the 69 as I am building it for my wife.


P.S. You don't want my 69, it's a beater! ;)
