talk to sam on here lsxperformance. i think that he can do it for alot cheaper… if not i know QUIK can do so also. mine is deleted and as long as it has no code none of the shops really bother. maybe some of the big placees like firestone might not pass it without cats. but most places are cool as long as there are no codes. dont know of many places (actually non)that will pas with a check engine light on.
