I just wanted to start a thread on sound deadening blankets Iíll be getting for my truck in the next few months. I just arrived to RC South, Afghanistan so Unorthodox Customs in Puyallup Washington will be doing the work.
A few weeks ago I was searching for something I can mount underneath my hood to help quiet my engine a little. I came across Advanced Thermal Products http://www.atpwrap.com/ APT currently has a quiet kit for the Cummins 6.7 http://www.atpwrap.com/html/dodge67cummins2009.html as well as the ISB 5.9 the kits consist of blankets that attach under the hood, valve cover, oil pan, exhaust manifold and turbo. I donít know the dB reduction.
Anyways they currently donít have anything for the 4BT so in Dec, unorthodox customs will remove my oil pan, valve cover, turbo, down pipe, and center dump exhaust manifold and ship them to APT to build a custom setup for my Tacoma.
I know a lot of people will like there 4BTs a little quieter and hopefully this kit will dramatically reduce engine noise, my Tacoma is very poorly insulated. Because of this my Tacoma should demonstrate how well this kit works.
The kit is pricy but hopefully if the dB is reduced enough in my Tacoma, that it might build enough interest for 4BTSwaps to have a group buy for other members of the site. Just FYI I am not affiliated with this company, nor will I receive any kick backs from them. I just wanted to pass this information along and once the kit gets put on my Tacoma Iíll update this thread with pictures and if I can find them a dB meter ill get before and after dB rating.
