hey dave, hit up accordhybrid, he's got an ex, maybe he'd be able to tell you for sure. I have a LX so my header came with the hole back at the end where it connects to the stock piping. Damn man, that sucks. Hope you get it figured out. Oh hey, get under the car and see where your o2 sensor is right now, if it's just behind where the downpipe connects to the exhaust piping, ur good, but if it's on the manifold or downpipe, ur screwed.
