Default Bogs at 3K RPM????

This weekend I and replacing the whole exhaust minus the headers with MagnaFlow. I bought these because I think my cats may be stuffed but if not its still a nice upgrade. My problem is when the car get the pedal pushed to the floor it bogs and doesn’t get past 3K RPM. But if given a slow acceleration it does (Most of the time). If not the cats what else could this be?

Low fuel pressure! Low load high RPM does not use as much fuel as high load high RPM, put a gauge on your fuel system and see if the pressure holds at least 42 PSI at WOT in drive. If the pressure drops you have found the problem.
