I ran a BBK H-Pipe w/cats for almost a year and never had a problem with the CEL coming on..... What finally set it off was the addition of the MAF/TA/Underdrive pulleys....

I can not say for sure whether it will or not.. If you get one w/o cats, it most likely will. However, you are 50/50 on the ones with cats... sometimes they set it off, sometimes they don't....

as I said, it didn't set off mine... but others on here put the same pipe on theirs, and it did trigger the CEL
