I found a thread but still not making sense. lot says 2" and some says 2.5".

one thread saying that cat diameter is 2" since exhaust pipe is 2"

one thread saying that from 4th was 2" and 5th gen is 2.5". So Im assuming that on the second thread since 5th gen has 2.5" exhaust piping the cat should be same diameter. http://images.honda-tech.com/set1//smile/emcrook.gif
