I’ve got a whipple, catless headers, X pipe etc. I don’t want to have to swap manifolds. It’ll be cheaper to register the car in Montana.

How did your tuner achieve this? My O2, CAT and HO2 are red because I’m catless long tube headers. If I could just get the tune to show them as unsupported instead of not ready I could pass.
