Custom Exhaust causing engine light to go off? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Hey! So im starting to believe that the Engine Check Light has been caused by my custom magnaflow exhaust. Anyone know if this can be true? if so anyway i can turn it off? I never touched the cats, only the mufflers. Thanks

i doubt its from the Exhaust, go get it scanned and see what the codes are.

+1 on not the exhuast, Check your codes first then lets us know what it says.

What does your custom exhaust consist of? If cat back only then it should not affect CEL.
did you recently refuel your car? many CEL lights is triggered by the gas cap not being put back on tight enough otherwise get the fault code read and go from there.
