Troubleshooting engine noise

Troubleshooting engine noise
So my truck was parked for several months while I was out of the area. After 2 days of driving in 20* weather, I realized my engine was way quieter than it used to be (99 24v 5 speed, basically stock). Previously I would have to set the stereo to #14 volume at idle, now I can hear it clearly at #10 during driving and this thing is straight piped.
Any thoughts as to what would cause that change?
It smokes black/grey during first start up in the cold as it always has. No damage to thte exhaust as far as I can tell, no serious loss of power ( I attributed the bit of extra lag to cold weather diesel fuel), and no oil burn off.

Noise from our rigs is usually the IP. I do know when I run 2-stroke oil in mine it is noticeably quieter than my usual dose of Power Service White Bottle.
Maybe you got a good tank of fuel, I have noticed that after a prolonged highway run on my truck it shuts off a lot quieter than shorter lower speed trips....
Don't know.

Cetane boost will quiet it down and the fuel may be aged a bit. What were you driving while gone? Or not driving! Maybe your hearing improved while you were in a quieter environment. I say that seriously.

I notice with my truck...It will run smoother and quieter at -20C,than at +20C...It's got to be the colder charge of air...
Thinking that could be the same with your truck...
