Default 2001 4.2 exhaust questions

I just installed straight through magnaflow mufflers and it too quiet. I also noticed that right side of the exhaust flows a lot less then left side. Is that because stock resonator is clogged or something?
How much louder will it get if i cut it off? I dont want it too loud either.
Second question:
Stock exhaust looks like it has a x-pipe before resonator, is that really x-pipe or pipes just welded together for stability? If it is x-pipe should i install another x-pipe instead of a resonator?
Third question:
Where is the o2 sensor located? on cat or before? Im looking to replace them with magnaflow but they dont have housing for o2 sensors.

Thanks

Keep the resonators and remove the mufflers and run a straight pipe. Removing the resonator will cause drone and will be annoying after a while.

02 sensors are on the cat and 2 of them are towards the front. To replace the front it needs to be thru the engine bay I believe.
