How to get more flow on my 91 F250 7.3 idi exhaust

I am picking up a 91 F250 7.3 idi tomorrow and I would like to strait pip it and get some new tire first thing!
I have been looking and havnt found any thing good on modifing my Y pip, I guess I can also only go as big as the manafold! So any one done anything cool some kind of performance Y-pipe?
I found a pip called Walker Y pipe on Thepartsbin.com but it looks like the same size!

91 idi isnt turbo. so one you dont want to straight pipe it considering you dont have any kind of muffling device.. at all.

turbo charger is a muffling device.. straight pipe without one will be like a gasser without a muffler, way too loud.

Hey guys Just got back from picking it up 250 mile trip did great but the long steep hills would set it back to 65 mph!?
So he lost power that cant be right! any one els heards of that?
It is so quiet now I have to get on all four with my head by the exhaust to hear it over the Engine, thats cool but if being load means more power then let er rip!
Seriously tho he lost power call him up and get more info, now I cant cut it lol?,
