i got this header and want to get it installed i dont want to do it my self since i will prob risk breaking the O2 sensor. What would be a reasonable price a shop should charge me to install it. Also how would i get rid of the CEL that will come on. Can i make the computer ignore the code so it doesnt come on? If a anti-fouler doesn't work then what? where would i place the anti- fouler? how much does an anti-fouler cost?
