I just put a B&B midepipe on, and i need to get rid of this CEL light, are there any foolers that actually work? And if not, is it ok to keep my CEL light flashing? Does my computer decrease in performance, or does anything screw up? Anyone?

 

and yes ive read enough CEL postings, does rotorygod or mazdamaniac have anything to say, as to any additions to the previous postings?
