I installed the Akrapovic exhaust on my 992 911 Carrera S. I wanted to use the OEM instead of these as I had powder coated mine a special color. These are brand new and have never been installed. Akrapovic part numbers are below. It is the left and right exhaust tips.

TP-T/S/25/L
TP-T/S/25/R
 
These sell for $750 each as replacements through various websites. My price is more than fair.
