Does anyone know if catless will pass CA smog?
Either way, I would recommend going to a place that offers a free re-check.
catless will not pass smog, with my wrx I just put my dp back on and was able to pass. I had a turbo, catless uppipe and all the other parts you usually need. I only put my stock dp on and left the rest.
