I have a 5.9 Durango and would like to have true dual exhaust (not a cat back system) but have been told the onboard computer isn't made for it. Suggestions?

As long as the O2 sensors are not messed with you will be fine, the computer will adjust to the flow diffrence.

no probs with the stock ECM, just leave the O2`s in the same location and all is fine.

www.gsmotorsports.com for a tru dual exhast setup is a good place to look.
