I used Resisto product self adhesive, modified bitumen, aluminum sandwich itís about 3-4mm thick, put in double layer on floor pan and rear wall do CC. Plus did door skin single layer. Also pulled foam backer rod through the door seals. Didnít do the roof or pillars, but made a significant difference. Also put a close cell foam layer on top of the Resisto on the floor pan.

Next truck Iíll try the Resisto sound deadening product, either way worth doing I think.

I used fatmat in my SD. Floor and rear wall and rear pillars up to the seatbelt. I think I ordered the thickest stuff they have available. Itís just sound deadener, not an insulator, but it helped some. Youíll never get it new truck quiet in there but you can try to make it tolerable.

Old96stroker,
Bahahahaa, knew that would pop up sooner than later. No question the 6.7 is quieter, more creature comforts, more powerful etc., only a few downsides. Taking it to the dealer for work on it, purchase price and maintenance cost.... thanks I’ll keep my old clattering noisy 7.3 that will have house construction sound insulation in it soon!
Cheers,
j

Got matting in the doors and floor. The area where it needs it the most is up behind the cowl trayó it is quieter (especially road noise), but still sounds like the 42r is sitting on the dash haha. Have bedliner on the VCs also. It will seem quieter for awhile , but itís a 7.3 .. 😉
