Right now I have a Straight pipe in place of the catalic converter I'm just wondering if anyone knows how to tune it so that there is no cel code

Go to AutoZone, ask for a spark plug fouler. Once purchased, drill out the fouler end, screw in your O2 sensor, and then screw the fouler/O2 assembly into your test pipe
