NOTE: Many of these products are for off road use only being that the cats are removed! We have gotten a hit or miss success on preventing the CEL for no cat from coming on. Most dont trigger, some have triggered 2 months later. Our metalic highflow cat will prevent it from coming on and will make you 100% legel as far as emissions go. If a CEL light worries you then we recommend you get a highflow cat. We have noticed no HP issues with the CEL light on.
