There is something wrong with my catalyst converters. I'm either going to have to replace them or just completely take them off! I know it's not enviroment friendly to take them off but it will save me hundreds of dollars! So i was wondering, what all is required to take them off? Do i just gut them and put them back on? Then i replace my O2 sencor with an O2 loop or simulator? What are the steps to doing this?
