You will never pass emissions with race or high-flow cats so dont waste your time. The sensors are very sensitive and the monitors won't be ready to pass. LC-1 works
I have headers and they have improved the low-end torque a bit. I dont care about the torque cause im always at 6000rpm in first and second gear. The car goes, feels, and sounds much nicer.
