From what I've read the E36 shorty style headers will bolt onto the m54b25/b30 blocks, but from there would require some exhaust work to mate the headers to the exhaust, so using an OEM e36 mid pipe for the header connection, then a cut/weld job to the existing E46 piping might work. I thought about pursuing this, then just figured it's a total waste of time and money for only about a 10bhp gain. Not the mention chasing after Check Engine lights and worrying over inspections.
