perhaps a catalytic converter? on 1997 Ford Thunderbird

My ford is getting very little power when stepping on the gas, actually flooring it

Many things can cause a lack of power, a plugged exhaust system is one of them. Spend the money for a diagnosis of the problem, don't try replacing parts on a hunch, it will cost more in the long run.
Other things that can cause this are: MAF Sensor, Ignition Timing, Camshaft timing, fuel pump, plugged fuel filter, transmission problems, throttle position sensor etc.
