All I've got to say is this stuff is amazing! I was really skeptical that it would even work, and toyed with where to actually install it, so to start off, I cut a peice big enough to cover the top of the muffler heatshield. Thinking it wouldn't do much to kill the drone of the Banks muffler, I really didn't want to spend too much time under the truck, but after installing this stuff, my truck sounds almost stock inside the cabin! I still hear the low rumble of the exhaust at low speeds, and it turns to a mild growl as I accelerate, but that drone that I had between 2500 and 3000 RPM is completely gone now! One peice of this stuff, 18" by 24" placed on top of the muffler heatshield really made a difference! All I can figure is that the heat shield itself was reverberating the drone to the inside of the cabin, and this stuff successfully killed that! So, if there are any of you out there that have installed an aftermarket exhaust system and found you have more annoying noise entering the cabin than you really wanted, this may be a really inexpensive solution!

The kit came with some degreaser soap, a roller and two 24" by 36" peices. I only used one and I'm saving the other to maybe put a double layer on later, if this stays put. It's self adhesive on one side and has a reflective aluminum heat shield on the other. Because of the tight quarters between the heat shield and the truck bed, I really couldn't use the roller, but was able to get a sponge soaked in the degreaser over most of the surface, and was able to firmly press the adhesive side against most of the top of the heatshield, and all the way around the edges. It felt as though it was sticking pretty good, and maybe aonce the exhaust heats the shield a bit it will adhere completely. Hopefully it will adhere just fine and stay in place. So, all in all I have to say I am completely satisfied with the results!

I installed some Dynamat on the inside of the front and rear doors in my crew cab and also along the rear wall of the cab, behind the rear seat. Took about 2 hours total, mainly because the first time or two taking the door panel off was a bit slow. Overall, very easy job, only simple hand tools needed. Easy to access everything and huge difference! The cab is much quieter, with almost no road noise now and the stereo is noticeably louder.

I was thinking of getting a Banks, and worried about the noise, so this is good to know. I did something similar on my G35 when I put a new exhaust on there, and it helped a lot also.

It's amazing how much sound this stuff absorbs! I had my truck undercoated today, mainly because I was getting paranoid with all the salt they've been dumping on the streets. I told them to spray it a bit thicker above the exhaust. The exhaust sounds stock now, except when I really get on it, but still it's nothing like when I first installed it! I like the idea of doing the inside floor panels and the back of the cab, that should have it as quiet as a Cadillac!

sounds like you are adding a lot of extra weight to the truck...with the undercoat, and the fatmat, and now thinking of dynamat. i think the extra miles per gallon you are looking for by adding the intake kit and exhaust will be nullified by the extra weight.

Can you post some pics of this Fatmat? I would like to see exactly where you placed the stuff.

I doubt I could get a picture of it, even if the truck was on a lift, because it's on top of the heatshield that's between the muffle and the truck bed! There's only about 2" of clearance where the mat is placed. It wasn't hard to apply, I just slid under the truck, measured the length and width of the heat shield, cut the material and then slid it on top of the heatshield. As I mentioned previously, it came with a roller to press it against the metal, but there's not enough clearance to use it, so I just used my fingers to press it firmly against the metal heatshield, and it seems to be holding just fine.

The peice I applied to the heatshield may have weighed a wopping 8 ounces, and I doubt the undercoating added more than a couple pounds, so I doubt it will have any effect on my gas mileage! I don't see any change in mileage whe I'm in the truck alone, or have my wife with me, so less that 3-4 pounds of added weight won't make a difference! Most folks have more weight than that in junk behind the seats! :lol:
