Not enough back pressure?

I'm not necessarily telling you to swap the setup out. You'll need a dyno to tell you which system is actually delivering better performance throughout your powerband. The "seat of the pants" meter is unlikely to be able to accurately analyze your cars true performance between the two.

Of course, if you're happier with one than the other, that's the ultimate test, isn't it?

I did the same changed out the factory cats for the offroad h-pipe mated to 2.5 flowmaster. THe car runs like a champ but is running real rich from inside the car I can smell gas fumes. Do I need make adjustments to my fuel regulator( AmFlo ).

Has anybody heard of AmFlo fuel regulators?

You would have to have a air fuel gauge to tell that. My car smelled rich too, your smelling the unburned gas thats being sucked out of the cylinder.

BBK makes a good one. Summit Racing has instructions how to install one. I wound spend extra $55 buck and buy the fuel pressure gauge

BBK has a high rate for rebuild requirements on their regulators, just my .02 cents. Aeromotive sells a good one IMO
