W211 E550 Exhaust
So I currently have no Mufflers,resonators,secondary cats and a X pipe .i was wondering if anybody has ever removed the primary cats and dealt with the CEL . I’ve never seen or heard of someone doing that on a 550 . I was thinking of doing it but I just wanna know how to deal with CEL. And what would the pros and cons be if I did do that .
