Hey so I have to take my car in to renew the registration. I was just going to ask some of you all with aftermarket parts on... I'm just wondering if I'll be able to pass my emissions check with my header installed. I mean I know I have two cats in there but feel like I most likely wont be able to pass emissions with just one, seeing that the header replaced my first cat. Have you all had any experience with it, do I really have to install my old cat back on?
