if yours was a M40 body with a 318 M40 engine, then it's small, but if your was a M40 body but a original 325i M20B25 engine, then it will align correctly...
cheers..
if got time tomorrow, it will post a picture for you.... you can it with a metal saw cutter..
correctto.... the M40 M20B20 has a single exhaust, wherelse the B25 is twin. so you can cut it bro. just treat it with anitrust and primer with some body seal.
