Hey, just wondering if any of you know if there are differences between the exhaust manifold of 4th gen and 5th gen preludes. I'm not sure but I've seen somewhere that the only difference is that there's an extra hole for a second O2 sensor for the OBD2 systems. Right? Wrong? Let me know.
Essentially, I'm wondering if a header from a 97 h22a will fit on a 94 h22a. (i.e. do the exhaust ports line up)
Thanks for the help.
