Newer high comp JDM motors have the same exhaust manifold as US spec 95 up manifold. It has no PAIR fitting on it and the EGR port has a screw in plug on it. I wouldn't even bother switching manifolds- intake ones if U have no emissions testing in your state. I currently run a JDM Rasheen motor in my SE-R with a HS Gen3 header that is about 4 years old. I love the power and it runs like a champ. Mike Jez
