4.0 Exhaust?

[Raxxor]

I was wondering which ehaust give this engine a nice rumble from idle all the way through the RPMS? My main goal is to get some better gas mileage and maybe some extra ponies. I see that many of you used Flowmasters and say that it gets kinda ricey. So which do you guys recommend for the 3rd gen 4.0L and yes i did use the search feature i just have some of my own questions. Any gas increase with your new exhaust? Power? Any videos would be great to. Thanks
