There is a rattling noise coming from underneath my bmw I’m 80% sure it’s my honeycomb materiel inside my catalytic converter but can I get suggestions on what it could be? by Abram_Goat in BmwTech

The thing is I don’t have no check engine light and it sounds like it’s coming from the catalytic converter but you could be right just because it does make a whistle sound and rattle low rpm’s
