I recently purchased a 2015 Audi S5 cabriolet prestige. I noticed the four stainless steel exhaust tips are heavily oxidized and were not taken care of during routine cleanings by the previous owner. As a result they simply look terrible.

my question is are they completely integrated with the exhaust and hanger system or can they be replaced with an aftermarket set of tips? Does anyone have any recommendations on replacements?

Great, thanks.
