its a bad idea really to remove cats as the computer reads on the o2 sensors

fuel air ratio mix to ecu computer. bypassing them is a crack of sh... and it will bring problems imo, and cats today hardly rob u of much power thats another myth.

when i did my truck i just renewed the cat y pipe system new 02 sensor.

your 5.7 will have multiple o2 sensors approx 3 i think or 4, and duel cats and pipe.
can be quite costly to replace, these o2 sensors are around $65 a pop.
