Approx 500-550lbs. of sound deadening materials in the truck with 400 sf GT-Mat and 100+ sf Dyna-Mat with either Dyna-Liner or 1" polyurethane foam rubber w/ MLV "Mass Loaded Vinyl" on top of CLD
1/2" of Jude sound proofing was used under all of the carpet as well
Stock Interiors Extreme Plush Carpet Kit also with the MLV 1/8" backing on it in the color is a light Gray
All 4 doors have been sound deadened inside with 1" poly foam rubber deadener over two layers of 115mil GT Mat on outer door skins.
Along with two layers of Dyna-Mat on the inside door skin as well as Dyna-Liner Over the top of that.
The door panels have 1” foam rubber on backside of all four doors for added measure.
Soundproofing is also above head liner also 2 layers Dyna-Mat w/Dyna-Liner on top.
The entire firewall is covered w/ 1/8” aluminized MLV over 1” Fiberglass insulation.
1" poly foam rubber on transmission tunnel plus two layers CLD on sheet metal floor of entire cab. Then again with 1/2" Closed Cell Foam Rubber w/ MLV and aluminum skinned facing under the cab itself.
The sound deadening was a game after a point and I went too far with it for sure. I don't recommend putting well over 500lbs of it in anything
I'm still fine tuning things today with CCF and MLV under the cab for improving on the sound control for the 2003 10 Vane turbo design.
dB meter was 76 dB at 70 MPH with stock interior
dB meter has 62 dB at 70 MPH after installing sound proofing
There is no engine noise in the cab since the sound deadening was installed with the exception of WOT inputs and tire spinning horseplay.
All and all with things combined the trucks improved interior sound levels and suspension upgrades it’s a entirely different experience for a old gray mayor.
Traveling at 75 mph really is a silent and smooth experience.
I occasionally have had people riding in the truck that think it’s a gas engine because you cannot hear any engine noise inside the truck. Damn Softheads.
