help me guys my sister has 98 accord her cat was clogged so i decided to open it up and hollow it out now the car is throwing a code im guessing its the o2 sensor code is tehre anyway to by pass this or do i have to get her another cat

 

i hate to tell you this but if you hollow it out you will need to buy a new cat ,,there might be some after market that are cheaper than hondas ,,
