Hey everyone. Now that I got my main issues resolved. I can work better on my last remaining annoying issue. My CEL light. This is being triggered due to not having CATS. I understand how that works, and why its triggering. My question; is those whom have the above set-up, with a Tune (BTR\SFR\ etc) what did you do, if anything that managed to shut that off? I was told to try and use Defoulers, but before I buy any again I'd rather try and find a simi-proven one that others have had success with and that fit properly on the test pipes. If anyone could include a pic, or a model number I'd be very thankful.
