How about a single 3.5"-4" exhaust? I think it would be easier to route on a high-boy than trying to snake duals under/around the NP205. My father ran dual 3" Flowmasters behind his 417 (bored 390 w 428 crank). It sounded like a dragster going through the woods, torque didn't seem to be a problem pulling 38"s with 4.10 gears. He was running heddman headers also. It pulled like an ox, pass most turbo diesels on hills with loads.

I've got heddman elites, flowmaster 40's that dump right under the bed before the axle. Its loud and resonates but I haven't yet the time to turn them out to the side. And I'd like to think I'm gonna put a crossover in there one of these years. Backpressure? my understanding is that if you loose enough backpressure you'll start smokin exhaust valves but I haven't seen it for myself. I've never worried about it.
