The service engine light stays on your car will go into SAFE mod and your car will run like crap.. You need to purchase MIL's to trick the computer into thinking you have Cats.

Hollowing out the Cats isn't the best thing to do because it screws up the flow of the exhaust. if you want to run with no cats I would get a off road H-pipe and MIL's
