putting the O2 sensors back will help with driveability somewhat but the MIL light will still be on with a code for the catcon malfunction.
may i ask why you took off the cats? if reason was for performance, you'd have been better off replacing them with aftermarket performance units with an aftermarket Y-pipe leaving the O2's in place.
evidently you're not worried about any kind of visual emmissions inspection.

I wasnt really worried about performance i was just trying to get a louder sound. Yeah in the county that i live in there is no emmision testing so i am not worried about it right now but prob later this year i am going to get hooker headers and the y pipe i already have a flowmaster Catbackk exhaust. thanks for the input though greatly appreciated

Did you take ALL the O2 sensors out? You do realize there is one set for Air/Fuel mix and another to monitor the cat for efficiency. The ones BEFORE the cats need to go back in ........
