So I just bought a 2001 RS. It has some sort of aftermarket headers, hollowed out OEM catalytic converter and a Tsudo catback exhaust. The OEM catalytic converter has been hollowed out so I bought a magnaflow replacement cat "OEM direct fitment. I will need to have this car pass emissions very soon in CO. My question is.... Is there a cat also in the headers? Do I need to also replace the headers to pass emissions? Will I have any CEL's from the headers?? Please give me some insight!
