Hey Guys,

I'm considering either a stage 1 tune, or stage 2+ w catless header. Having to remove/re-install a header to pass is not something I'm interested in. With map switching capability, no issue with a tune alone, but will I pass with the primary cat in the header gone? Would I need to switch maps to pass? I'm in Houston, so we have some additional standards, IIRC.

Not sure how the standards are in Houston. I have used 2 different dealers to get an inspection on my car in the DFW area and pass every year. Catless header, catless front pipe, OFT stage 2+.
