Whatz up here is the problem my car hesitates when i am going on the interstate or when i stomp on the gas. my catalittic converter broke off inside so we reamed it out and hollowed out the catalittic converter that is when this started my question is could that be causing the misfire because tomuch air is going out of the exhaust and hitting the o2 senser if it is not what could it be thanks in advance

so how would that do it the senser is reading to much air and messing up the fuel

No, you lost back pressure, so your header isn't scavanging gasses from the other cylinders. So at higher RPM's the exhaust system can't pull the gasses out of the other cylinders fast enough, and it bogs out.
If you don't have a blinking CEL, then your car isn't misfiring, its just hesitating.

that is exactly what it is doing could you bypass the senser or would that be pointless ? the reason i ask is someone told me to do that!

Whoever is telling you that really doesn't know how your car works. You can't "bypass" the sensor. Just get a new cat and put it on. You can get them pretty cheap usually. Just fix it the right way, instead of doing it half-assed to save a buck or two. The O2 sim you would need to "bypass" the sensor (simulate it actually), would cost just as much as the cat itself.
