Well, you probably need to search on this one. There have been many threads on exhaust and the variations are in-exhaustable.

I don't know jack about exhaust on these trucks. I just modded my stock exhaust for better sound (see my gallery) and am waiting for the muffler to rot off ( but in 12 years the orignial is still good ) so's I can put a nice free flowing muffler on and a short pipe turning out in front of the wheel.

I have a gutted second cat with a glasspack exiting in front of the passenger wheel. It sounds good. I'm going to experiment with a 1.5" pipe straight and see if it sounds any different.
