I'm keeping the stock tips on our 128i (Montego Blue), but I just think the black chrome tips are a better match for Mineral Grey.
I wonder how the chrome M tips perform. The stainless/burnt tip on my S2000 exhaust still looks like new with absolutely no maintenance (the pics are my exhaust but not my car...I purchased the demo exhaust): http://www.gotuning.com/product_info...oducts_id=1283
