What I have found (with myself personally) is that the louder the exhaust is, the less useable power I have since I stay out of the throttle to keep the racket down. Also IMO it is harder to tune an engine when all you can hear is the exhaust and not the motor itself.
I wouldn't sweat the muffler, it's not like you can go out and buy a more restrictive muffler than what comes from the factory. The PO may have gotten the truck with a cheap aftermarket muffler or no muffler at all.
