Really interested to find out how much of a difference it makes. How many hours would you estimate it has taken?
What have you done to your 2nd gen Tacoma this week?

So far I have 93 logged hours of straight labor, not including setup and cleaning each time. The roof, floor and back cab reduced noise by 2db. Once I'm done with the doors I'll be able to get a final noise reduction measurement.
Finally finished all 4 doors and that is the final stage of this project. Very very glad to be done with it lol
Just added third gen door seals between the two doors on each side, and installed the updated tsb front door seals to further cut down noise in the cab.

3rd gen door gap seals:
67895-04010 - Right Rear (Access Cab)
67896-04010 - Left Rear (Access Cab)
67895-04020 - Right Rear (Double Cab)
67896-04020 - Left Rear (Double Cab)

I was able to get that final decibel reading today.
Stock 78.9db
Sound Deadened Cab (doors still stock) 75.7db
Sound Deadened Cab & Doors Plus New Seals 74.1db
In other words
Sound deadening the cab dropped 3.2db
Sound deadening the doors plus new seals dropped 1.6db
Total db drop after full sound deadening project was complete 4.8db

That's a meaningful decrease in noise. Does the remaining noise that's still present seem to come from the same locations that you've already addressed above, or it something else like wind noise that would be difficult to address without something like acoustic glass?
Replaced the compass/temp gauge that went bad.
The updated part has different internals

The only thing I can really hear now are the 35” mud terrains. I balance & rotate every 5k so they are flat and not too loud. Also, the glass in the truck is thin and lets in noise, but nothing can be done about that.
I ran the db test in my wife’s 328i BMW, and it was louder than my truck by 1.8db lol. Total weight added was only around 55-60lbs
Quick and easy wiper blade diy (only works on oem blades)
I did the a/c drain mod which reroutes the factory drain down below the frame. Not sure why Toyota was ok with water dripping onto the frame. Especially after they had major issues with frame rust on the 1st & 2nd gen Tacomas lol.

Any thoughts why they decided to make the extension hose a narrower diameter than the oem drain hose?
Not sure to be honest, but he's been selling them for a few years with good success. You can also grab a brass union barb of the same diameter and use larger hose to run it down below the frame.

Installed this Mishimoto transmission cooler kit on a friends truck. It went on super easy and he reported a large drop in transmission temps.
I also got around to replacing the torn factory engine splash guards with some aftermarket neoprene replacements by rad rubber. The oem’s are like $200 versus rad rubber for $70. Hopefully they last 
Magnefine power steering fluid filter installed inline with power steering return line. Filtered out hard metals from the system to prolong the life of the pump & rack.
At 220,000 miles and I've just replaced the 3 idler pulleys and the bearing on the tensioner pulley. The tensioner itself is still good. The truck runs as quiet as new and you can basically hear the injectors tick.
I used the following OEM parts for the pulleys:
(x1) Idler pulley - 16603-0P030
(x2) Idler Pulley - 16604-0P011
I used the following OEM bearing for the tensioner pulley:
NSK BD17-31DUM
Old pulleys:
