Exhaust routing on lowered trucks?

[AKChevyman]

Ok I have a few question I am not quite there yet but I am curious on how you guys routed your exhaust I need examples I am running airbags and I will need room for the tank and pumps later but I want to run dual 3" for the Big block that is going in the front. I don't plan on changing the cross member that the trailing arms attach too either. Any help you guys can provided will be helpful Oh also I don't plan on going past the rear axle with it becuase I am running a custom fuel tank at the rear of the truck. SO the pipes will dump right in front of the rear wheels. so I guess my main question is do I stay in the frame or go out side right from the get go. as always any advise is good advise thank you.
