Is it worth it? Yes. Did my entire 4Runner, floor, walls, and ceiling, front to back, and then added wool insulation to the floor, walls, and ceiling. Not only great with lowering interior noise but also significantly improved interior temperatures, cold or hot. I live in Arizona and mostly overland in the southwest. Thanks for sharing.

@@woody721 I apologize since I just saw this today. I hope you found an answer somewhere else. Again, I apologize. If you haven't, I used a single layer throughout, including the roof. This summer, 2023, I slept in my 4Runner during the day while I worked at night. With a 5k BTU AC window unit I slept comfortably the entire summer with outside temps reaching 119F. I would say the insulation is efficient. Again, I apologize for missing your question.

@@jatorresrvI already had the floorboard done by a shop. I had it done to reduce road noise because of my audio system. I ended up reducing flex from the roof by doing the roof myself. Kilmat was used for both applications.

Great work. Some other areas to consider: * Tires themselves generate a lot of noise. Find a balance of on road / offroad needs, but a well-designed on road tire will be quiet, grippy, and lower fuel use. * Exhaust and engine isolation. Make sure mounts and hangers are new with good quality soft rubber. Avoid solid mounts. * Test and retorque suspension and body nuts and bolts. * Pure exhaust volume. If modified, a loud exhaust can reverb back into the vehicle, especially droning. Consider retrofitting a late model exhaust from a scrapyard. * The firewall itself in the cabin. Hard to get access to all the firewall, but it faces all the engine and open road noise. * Other panels bolted to the body but not a part of the cabin can transfer vibrations to the cabin structure. Hood, front fenders, truck tray, sidings, and tailgate. * Multi-frequencies. Different isolation products only reduce sounds within set frequency ranges. Apply additional products where it counts. Use a decent sound spectrum analyser to know which frequencies are still strong. * Wiring hardness. It is heavy and can move and vibrate against the body. Wrap it in a fireproof felt product. * Good luck, it's a fun challenge. 🙂

Great tips for anyone else looking to reduce road noise!

The ridged rollers are nice because you can easily tell what you have already rolled.

Doors, A-pillars, and then the back panel next to the truck bed are the biggest noise contributors, imo. Also, dB is logarithmic, so you can't use percentages unless you know how log works...

Under-body can be achieved by getting it rust proofed with one that also has a sound deadner in it as well if ya take it to the right place.

Very nice decibel reduction! I have thought about this but wasn't sure I was up for all the work.

You should have added a layer of closed cell foam over the butyl layer. That makes a difference.

Thanks for the video! I'm curious if you noticed a bigger difference at lower speeds. That seems to be the common theme in before-and-after dB test videos I've seen.

Hey! Aside from a great video what was that rear view mirror do you have? I like it

@pnwxplore

The mirror was awesome! It’s no longer sold on Amazon, but If you search digital rear view mirror on Amazon, you’ll see a few options. It doubled as a dash cam as well

I watched a walk around on another channel where the now owner of tiny rig Co talked about he three layer system he used to sound deton his Tacoma. Then watched a bunch of other videos to understand usage of the 3 materials and I think it made a huge difference in my truck. I know the pain you're going through with how much work it takes to do it but trust me that rear firewall will make a big difference.

@@pnwxplore not only that, but a close cell foam is what reduces interior noise the most on top of a vibration reduction material like you laid down.

Great video, thank you. I've got an AFE side exhaust, and the drone is finally annoying the crap out of me, especially at 85mph+. Do you feel this will help deaden that with the thicker mat, & the back wall?

It’s likely to help a bit, but a better investment would be to have an exhaust shop install a resonator.
