i posted about this a couple days ago and someone told me that a greddy header for a civic si v tec would fit on my civic se. but i would have to get the matching si cataylic converter. i was wondering if the only readon i need the cat is so the flange bolts will line up. if so wouldn't it be easier to just cut off the flange connecter on the cat and weld it back on in the right spot for the header? and an ex catback exhaust will fit my body type right?

 

anyone got any idea at all?
