I'm just going to run it long enough to pull it up on my trailer and shut it off.

Won't hurt the engine at all, if thats your concern. When your new exhaust is on, the computer will simply relearn its fuel curve. If the exhaust shop isn't too far away, you can even drive it over there, just stay out of the throttle. Make sure the manifold exhaust isn't blowing right against anything important either.
