Ok my header doesn't seem like it lines up with my motor I have a 95 accord with jdm f22b motor and I got a massive leak and the downpipe and cat don't really line up should I try a header from an h23 or from an f22ax

 

Do you have the dohc f22b? Which exhaust mani are you trying to use right now?

 

Yes its the dohc and I'm pretty sure the header I have on now is for an accord because of the o2 sensor location because I don't think preludes have the o2 sensor on the manifold

 

What year Accord is the manifold from? 90-93? 94-97? Did it come with the motor or did you get it from somewhere else?
