I was wondering if the 3" Intense down pipe gives a CEL? Obviously if you remove your cat, you would get a CEL, but I heard that this pipe moves your o2 sensor up to try to prevent a CEL. True?

Either way, if I do get a CEL from this o2 sensor, would this effect performance?

 

You can turn the CEL off with HP tuners, that's what I had done. Doesn't effect my car at all.
