I believe you are saying that with a high flow it will not pass the smog emissions test, but if I do not care, then it will work?
I was hoping both cats would be on the catpipe, because then I could swap out before I would go for an inspection, but if I need to mess with the UEL headers to make a high flow system work, I'm not sure if I will go through with it. UEL will cost more and I'll have the same flow as the EL stockers.
PS - Cant find crap on stock 2.5i CFM anywhere.
