Will 98 m3 cats and exhaust fit a 94 325is?

I don't see why it wouldnt work. Cant you pretty much put any cat and exhaust on any car if you have the skills to do it?

I think they'll work. If you want you can get car sound, they're fairly cheap. My brother got a free flow from them and the material inside busted loose after a year, so we just knocked it out, no more rattle.
