Exhaust question.
So I'm still learning more about my truck before seriously jumping into making it mine.
I've read a lot about straight piping, and aftermarket exhaust systems on these old trucks. And I did a search and didn't get the information I was looking for.
The other day I was in traffic and a straight piped cummins drove by, and it was just ****ing obnoxious, to the point where I had to roll up my windows till it was gone.
I really like the low end growl I've seen some of the old idi's do, but not that obnoxious deafening sound when your going 100 km/h down the freeway, and all the research I've done is entirely inconclusive, so I figure I'd throw it to some of the *cough* Older *cough*.... Wait I mean wiser!, members for input, I'd prefer to not spend $500 on an entire exhaust system, and would much rather something I could build/customize/fab myself. I'm also thinking of moving it in front of the rear tire, though I've heard that it makes it louder (Again no real proof to random internet comments).
I appreciate the information.

If you don't have a turbo, you don't want to straight pipe it if you don't want outragously loud exhaust. Two of my boys took my 90 to the exhaust shop, and came home with it dual straight pipes on it. A couple of months later one of the boys got pulled over by a state trooper for loud exhaust, and that was during the motorcycle rally at Sturgis. Louder than a straight piped Harley.

Yeah I have a non-turbo, but scouring CL for a used one, or parts truck with one.
I'm not sure how loud they can get, but I know the local limit in the city of Vancouver is 93dba for a diesel engine, so one assumes most of the lower mainland is the same. I don't want to be at the limit, but I want a little more noise from this thing when I rev it.
Poocher, I'm gonna have to jump under my truck tomorrow to take a look at what I have to work with, do you have the cat still in, or is it gone as well?
Something like this would be perfect.

Well I don't really want noise, the gf will bitch over it if it's too loud (Joke, you think....), just wanted a nice deep roar when I gave her, but not obnoxiously so.

My exhaust rotted off at the Y tube flang under the cab. I ran that way for 2 years or so. At speed conversing, with the passenger was just not possible. At idle it is quiet as can be. I took it easy passing houses in the early morning. I passed a lot of LEOs coasting with clutch disengaged. No problems. 
I ended up cutting an entire exhaust out of a PS equipped van, cut and pasted it to size as a welding project for class. Fabbed some hangers, hooked it up and ran it. It's nice to be able to drive without ear protection.
