Used Akrapovic Titanium Exhaust and OAP's that came off my 2021 Boxster GTS 4.0. Moved on to a 911 so I no longer need this exhaust. There are a few scratches on the bottom of the tips but other that than in good condition given the exhaust has approximately 38k miles on it. I would prefer to sell them together but will consider selling the OAP's separate from the exhaust. Exhaust alone retails at $8k and the OAP's (which are no longer available) were $3,800. I can send links to videos where you can hear how awesome this exhaust sounds.
