Don't need to spend all that dough for soundproofing vents.

Pictures:
1. Buy Grout Sponge - Lowe's/Home Depot - $1.96
2. Mark & Cut sponge 4" X 6" - Then cut in half
3. This is how sponge will be inside on panel. I used Silicone adhesive on side going against the OUTSIDE panel
4. Clean Panel before installing sponge.
5. Replace vent, DONE!
(Holding hand up) My question is; this material goes INSIDE the vent hole sticking to the wall of outside panel, the material being thick enough that when the vent cover is reinstalled the foam material fits against the back-side of the vent cover ??

Yes!! Just like OEM.
Foam material from GM is:
4" X 6" X 1/2"
Cut the Grout Foam the same.
If you have a mid 05 or any 06, ALREADY DONE from the GM factory.

Just did my vents but the sponge wasn't 1.96 it was 1.78 at lowes waiting for the silicone sealer to dry a. It before test drive have yet to install matting though went for a drive ,yes my r was out ofthe garage(jeff) it works great if the road and tire noise bothers you this is s must
For anyone considering doing the same thing with the vent sponges, you can go to a paint and wallpaper supply store and buy the grout type sponges, they use then for wallpapering, that are the correct dimentions. 4X6X1

I'll get around to soundproofing my top compartment after the Flagstaff Rally.
I did the inner quarters two years ago just before the Texas Rally and we did the doors at the Rally. It all helps but inside the truck it still sounds like a window is open when I drive down the road.
I really notice this when I start driving it at the start of the season but after a while I guess I get used to it.
None of the 03/04 have vent soundproofing and the first half of 05 production.
GM didn't start vent soundproofing till mid 05.
You can buy the kit from your Dealer at $40.00 or you can cut a ceramic sponge to 4"X6"X5/8". For about $1.96 plus clear silicone caulk adhesive.

1. Ceramic Sponge - Home Depot
2. Cut to size
3. Remove Vent
4. Clean outer wall panel, apply adhesive, press to outer wall and replace Vent.
5. Here is where the noise comes from driving down the highway.
I'd be hesitant to use any old sponge. Sure they will block to noise from the rear wheel coming back up through the top stowage compartment into the cab, but consider why the holes are there... flow through ventilation.
Yes, they allow the pressure to equalize so the windows don't bulge, and the door will open or shut. But more importantly after GM eliminated vent windows, these hole allowed the stale cabin air to escape, so fresh air (heated or cooled) could enter the cabin.
You wouldn't want to impede the exit of those refried bean gasses.

Yes, very good points and I didn't use any old sponge, I used a ceramic sponge which will not retain water, plus last a long time.
That said, the venting with sponge material was done by GM Factory, so I concluded that they didn't see any harm is soundproofing the vents.
I didn't do anything different than the Factory except substitute the same type material.

And you saved many members some $$$$. Way back when I asked a GM dealer how much to do the install and they wanted $150 plus materials...so following your directions I just installed them myself.

What is the best way to rmove the panel? I tried to pry it with a screw driver, but it would not come out. I did not want to get too strong with my efforts. Is it hard to reinstall? Thanks!!!!

Oh, when you said ceramic sponge I thought you meant a sponge for grout on ceramic tile, I didn't realize the sponge was ceramic. Didn't know they made flexible ceramic you could cut easily.
Personally, I welcome our new ceramic overlords.
The reason the dealer wants $150+ is the Chevy procedure is to remove the rear wheel and inner fender well, then work from the outside. This job would be a flat rate mechanics dream, if he was aware of this method.

You are right about mechanics dream, remove rear tire, remove wheel liner to put in soundproof! I learned about the vent removal at Texas Rally.
And OKay, I stand corrected, kinda, the sponge is a GROUT sponge and not ceramic. I know that because I dropped one and it didn't break!
I have the GM $40 soundproof in my R that is why I started looking for a substitute that did the same but cost less.
You defiantly done good, providing those of us that aren't savvy enough to stray from the GM manual/parts counter, with a cheap, doable, solution. I just wanted to caution people against grabbing Mama's kitchen sponge, and look around a little, like you did.
Also, this method can easily be reversed, before going to Barrett-Jackson for the big pay off.
