So, I just bought these to try out on my exhaust setup and ended up getting my HFCs replaced under warranty, so I don't really need them. No issues, standard VHR/HR flange ART pipes in good working order.
I'm in Pittsburgh and can ship on buyerts dime or meet up within reason. Asking 550 shipped obo. Would also trade for catback exhaust components/parts or used coilovers for a 370/G37 coupe.
Can send more photos on request.
