will this throw a p0420?
hey guys...I have one final question before ordering parts....I have a 96 hx and need a new cat/exhaust manifold to pass inspection...I think im going to buy an aftermarket header and a universal carsound obd2 compliant cat. I know I'll have to extended the secondary o2 sensor but I need to know if I do this will it throw a code. I don't have emissions where I live but it won't pass with a check engine light. any help is appriciated

thats what I am hoping...I'm just hoping that the header wont mess up my primary o2 cause the 5 wire o2 for my hx is like almost $400....so has anyone out there thrown a code because they relocated the secondary o2?

Re: (spray_bombed)
One final thing...If i put a new cat on it and it still throws a po240 code and I pull the bulb for the check engine light...will it affect the way my car performs in anyway? because doesnt the secondary only measure the cats emissions output?...thanks alot
