Hey everyone,
Just picked up my first used 2018 M5 and ready to detail and protect it. However I had a question regarding the black exhaust. I normally use P21S for all my details but have yet to come across the black (matte??) exhaust.

Any recommendations and would you know if P21S would work?

Thanks in advance

im assuming you have a first edition with the sport exhaust that comes on the M5C? If so its not matte, its black chrome. Clean like normal. I use brake cleaner and a soft brush. Would also recommend removing them, cleaning them thoroughly and applying some Dr. Beasely metal polish. It's like ceramic coating for hot metals. I use it on my stainless weber grill, stainless appliances, and exhaust tips. Works great.
