Installed FatMat and the sound difference is amazing !

Installed FatMat MegaMat in the trunk to kill a little solo exhaust drone. This butyl mat not only got rid of the 2k drone from the exhaust but made the stereo system sound so much better than before I would have installed just for this ! Tried some other sound deadeners before but they never really much of a difference . Bought 25sqft which was more than enough to line the trunk and side walls.
Before changing out your speakers this is worth the time and $ !

Excellent! FatMat is good stuff...

Sound deadener for some reason is so easily (and often) overlooked... most of the time you can make an "ok" set of speakers in deadened doors sound like really expensive speakers in un-deadened doors... best bang for the buck on any SQ oriented install.

I noticed yesterday that it seems like 75% of the road noise is coming from the trunk, heck, when I came to a stop, I could hear fuel sloshing around in the gas tank! Its no wonder some guys complain about the drone, when there is zero deadener in the car its almost as bad the the windows down.

I remember the night I got my car and posted here. I drove about 5 miles from the dealer and said to myself WOW this car is niceeee, then I got on the highway and at first I thought the windows werent closed, LOL, then I said to myself, Man this car is noisey on the highway. I added the OEM trunk mat, that helped a tiny bit. I think one day I might get a fatmat and install it.

fatmat can be cut and shaped/bent/formed around corners and whatnot. and it is an adhesive butyl rubber so it sticks really well to clean surfaces and wont run or get sloppy like the asphalt based deadeners...

stay away from the asphalt deadeners ... they stink and when they get hot they can melt and drop off.

Second Skin is my personal favorite for deadeners but like with everything, thats just a personal choice and what I will be using on the Camaro... I have used the damplifier pro - good stuff but I want to try the spectrum sludge thats a paint-on sound deadener... see how well it works.

Very nice. How much did the 25 square feet you purchased weigh? Just curious because I am starting a sub box today and want to keep the added weight in the truck to a minimum.

I am also going to isolate the 6x9" Boston speakers in the truck due to adding a sub.

I used second skin, damplifier pro. Highly recommend this upgrade. Also when doing this get a pair of glass cutters gloves, they are the cotton gloves that have kevlar on them. The foil on the matt will cut you up.

Think maybe you can post some pics to see how you covered that trunk, and how much 25 sq ft takes up? Thanks................

Fatmat has 3 types, so which one would be the best for the trunk?

Megamat was the one I chose, It is made of Butyl and then foil backing is not as sharp as others, making this install very easy. After a lot of research on previous cars I found that the Butyl mats were the best. http://www.fatmat.com/bulk/megamat/25.html

Doing the curve surfaces does take time and you should do this when the temperature is in the 70's since it will get very hot in your trunk. Did mine when it was in the low 80's and I was sweating up a storm. But it is a project even a novice could do.

I covered the spare tire well, the floor and back wall in the trunk with 25SQFT. This was suggested by the customer service people. There already is vibration dampening patches on the side walls. I have been very happy with the coverage that was recommended.

I will try and get some pictures this week if I can break away from work

i went to lowe's , got a 25sq ft roll of thin reflective insulation for $12.

covered the trunk only and it reduced the noise from my flomaster exhaust so much i'm going to take it out or remove half of it.

i can't even hear it roar anymore....sure the radio may sound a little better, but the car sounds like it did with the stock exhaust :(

so be advised!!

It was 3/8" inch thick with aluminum on both sides. Called reflective insulation for water heaters. It was in a 8" x 30ft (25 sq ft) roll or a 16" size. I got the 8", cut pieces to match the trunk liner and just ducted taped it together. Threw it under the trunk liner, and no more rip roaring exhuast notes!! :( Took 10 minutes to assemble a perfect trunk cutout and install.

Will take 2 minutes to remove and cut in half to get some good sound back

Anyone have any recomendations of sound deadeners, quality of deadening versus weight?

I found pipe insulation.
It comes in 12" rolls 15' long.
It has foil on one side, and what looks like double sided foam tape on the other.
Cost $12.
Thinking of turning my trunk carpet over in my house, and covering the back of it with this stuff, that way I can just remove the carpet and do something else if I choose to.
This stuff is really light, and I prefer to do a lightweight install.
That butyl stuff must be quite heavy.

I couldn't find anything close to what you all are talking about in either Lowe's or Home Depot.

I think I might have seen the foam with foil on one side for the pipes. I looked near the hot water heaters and in the insulation area and the duct work area.

I was looking for the bubble wrap stuff with foil on both sides.

What section is it in?

I found some at Home Depot in the water heater section. It was in a role,about $14 and One did most of the trunk for me. Im going to remove the battery and do that part and im done.
