[QUOTE="Mustang4vSVT, post: 13416131, member: 37534"] my 01 cobra did not pass with a magnaflow catted x. Shop said they legally cant pass it (dunno how true this really is...it is california) since its after market cats and has 2 instead of 4 cats like it has stock, but where looking the other way when it came to that. It still failed the sniffer. Barely. I just put the stocker back on and passed. Ive heard of a lot of "performance high flow cats" doing so. [/QUOTE]
