I've read a variety of differnt suggestions on pipe diameter and muffler choice, so I'd love some input that everyone can refer to later.
Diameter: from header to x-pipe to muffler and muffler to tip? I've heard a variety of things. Someone told me to keep it 1 5/8" between the header/x-pipe/muffler and run 2" after that in order to build up enough back pressure and efficiently scavange with the x-pipe which should be located within a foot or two of the header outlets. Lots of people seem to like the flow masters, but which one? 40, 60, 70?
I'm torn between going 2" from the fenton's all the way back and doing the narrower pipe in the front.
Any thoughts?

Does anyone have any pictures/suggestions on routing the pipes, locating the mufflers and x-pipe?
I've got a booster/dual master, t-5, 10 bolt posi (3.42:1) and plan to add a trailer hitch. So, I'm definately going to have the pipes come out just behind each rear wheels.
What about using resonators in addition to the flow masters?

60 series = Not as loud, still resonates a little
70 series = A lot more tame less resonance
If you run them back together you'll have to cross over with one at some point...in my opinion that looks cheesy. I think it looks better with the pipes ran on opposing sides. Later
