Which setup would flow better?
I have an 85 F-250 X-cab 4x4 with a 460, and I was wanting some opinions on my exhaust ideas. I was thinking dual 2.5" with an h-pipe, then running up through the bed to 3-4" stacks. If I can't find a shop to do my stacks, then I was thinking 2.5" duals, h-pipe, and then 4" tips out behind the rear tires, or 2.5" pipe into a single 4" pipe, then just dual out the 4" pipe after the axle and exit behind the rear tires again. The motor is stock, with 109,000 miles, would the pipe diameters I have suggested be good, or should I go with something different? Just so you know, there will be no mufflers or cats on this truck, so that is not a factor.

No mufflers or cats? Well, that makes it simple. I would stick with true 2.5" dual pipes exiting after the rear wheels. Use an H or X pipe with it. This setup will give more torque than will the 4" intermediate pipe......
