If it has factory exhaust, leave resonator (thing you would think is a catalytic converter) on and run straight pipe from there. The resonator looks like a glass pack inside, and keeps the truck quieter. After the resonator the exhaust expands to a larger size before going into the muffler, just run that size the rest of the way out. If you are lazy like me, you just run it straight back and turn it down before the axle. This would set your dodge up like mine, except I only have 60hp adder. I never get to 1000 degrees and I think you get to go to 1250, so I would think this list is enough to run the 120hp, and of course the ottomind will cut back fuel before it gets too hot anyway.
