Exhaust Questions

[ajpthng]

As most of you know I'm wanting to put an exhaust system on the Dodge, I've seen several set ups for dual exhaust and many different opinions on the best set up. I thought I would post it up here and see what kind of answers I get. My truck has 2 cats then a Y pipe and 3 mufflers and many bends before it exits the back of the truck, it has potental for a true dual because of this setup. If I were to go true dual what would be best, straight back, staight back with an H or straight back with an X? Or should I leave the Y pipe and run a single in dual out or a single in single out?

What would you do and why? What would be best and why?
