Excess gas coating? Do you mean unburnt fuel is entering the converter? If so, then the fuel/air mixture is too rich, or you have a cylinder that is not firing.
Yes it did.

There are not two catalytic converters. Working towards the muffler from the flange, you have a RESONATOR, a CATALYTIC CONVERTER and finally a MUFFLER.
At the rear of the engine and the second one is in the middle infront of the muffler
Bypassing the catalytic converter on a Ford F150, or any vehicle, is illegal in many places as it violates emissions regulations. Additionally, it can lead to increased pollution and may cause engine performance issues. If you're experiencing problems with your catalytic converter, it's advisable to consult a professional mechanic for repairs or replacements rather than attempting a bypass.
bank 2 is the drivers side of the engine , and sensor 1 is near the engine before the exhaust passes through the catalytic converter , sensor 2 is after the catalytic converter
drivers side of engine , downstream from catalytic converter
Check to see that your catalytic converter is not full. Otherwise get your engine tuned up.
On a V6 or V8 engine, the passenger side cylinders are bank one, so the catalytic converter on the passenger side will be bank one. The driver's side is bank two.
Catalytic converter efficiency failure.
bank 2 is the drivers side of the engine bank 2 - sensor 1 - is before the exhaust passes through the catalytic converter bank 2 - sensor 2 - is after the catalytic converter ( downstream )
Let a professional do this. You save very little by DIY.
