taken from a 98 BMW M3 coupe with ~125k on it, PA car. I believe coupe and sedan exhausts are interchangeable. I can tell you an e36m3 exhaust will fit an e30 with slight modification, I had one on my s50b30 e30.
$115 for cat-back, $60 for midpipes/cat (I can get that or more for it via scrap but it’s easier if I don’t have to get them apart).
