FIG, the RS60 tip looks really good in person. It is a nice brushed stainless steel look.
The tip you are showing in the Cayman picture is the "Sport Tip". And I am not too crazy about that one either.
But the chrome "S" tip looks really good:

I am thinking about selling my chrome "S" tip and buying the RS60 tip this summer.
The stock OEM tip on your car dis-colors, and you can clearly see this in your pictures. That's why I think a different tip would have looked more crisp and have the proper color.
