Default 2000 4.2v6 trouble

I have a 2000 f150 4.2 v6 and I think I have an exhaust leak (different sound lately) but does that motor need a certain amount of back pressure. The motor feels like it is hesitating, now I am thinking it is an exhaust problem and not a motor problem. does this sound about right????????
thanks

Possibly. A partially clogged catalytic converter can cause the engine to feel like it is hesitating, too.

If you think it's exhaust related, I would try disconnecting the exhaust before the cats to see if that helps the engine run better.
