It sounds like your looking to do the same thing im doing. 89 F350 single cab, 5 spd, dually. I just had a strait pipe put on so i can get through inspection and it is really loud and it does not sound that great. I dont know about you but i like the diesel sound. it sounds the same at idle but once you get on the gas it sound like it is a loud gas engine. I have been looking for some after market exhaust kits for mine but it looks like im going to have to make something up.

If you have a Truck Pro
anywhere nearby, they carry a great selection of large pipes and fittings. Straight pipes can be pretty rough with no turbo. But you can put straight through big truck mufflers on and still have a good sound without being loud enough to shake the fillings out of your teeth.
I did my whole system in 4" pipe from the downpipe back with a 36" straight through big truck muffler for around $160 ( could have got by a lot cheaper but I used the high dollar pre shaped band clamps on all the fittings)

my buddy has a '90 7.3 idi non-turbo. he ran 2.5" straight pipe off each manifold then elbows up through the bed. in PA we have to have heat shields. he ran the 2.5" pipe up to the top of the bed rails the set 5" from the bed floor over the pipes. also in PA stacks on a diesel truck function as a muffler. that is what the inspection stations tell us atleast. his truck is loud at full throttle and crackels but normal driving it is not that bad.

I made up a 4" exhaust for mine. I used an ATS muffler (huge!) that had two outlets (see my gallery for a few pics). It sounded great at idle but was horribly loud when the RPMs were up. I finally capped off one outlet and ran a single outlet tailpipe exiting in front of the back tire. Still loud on acceleration, but sounds much nicer, but lost that nice, resonant idle. When we get fair weather again and I'm feeling ambitious, I'll put the second tailpipe back on and record it, then record it with the single outlet and post the files somewhere.
