Looks great, good job! Did you only do under the front seats?Complete floor sound proofing done.
Review: Noico makes a good product, this is their 80mil stuff. One package was enough to cover 90% of surfaces under the driver's, passenger's, and rear seat sheet metal. I put a little in the back under the center section just behind the rear seat, but have plans to possibly route some air compressor stuff on the sides at some point, so left all that untouched

Takes a little doing, but this stuff is awesome. When I first started driving, I thought the engine wasn't on, then I thought I had a hearing issue. Around town, 45mph or so, markedly quieter. Conversations are easier, music better, feels much more vault like.
However, add a lift, 37 inch km3's, and highway speeds, noise is back , mostly wind noise and tire drone. But that's expected, as this vehicle has the aerodynamics of a brick with 3 kites and a windmill attached.
