I am thinking about selling my stock GNX exhaust, from after the cat to the rear tips. The mufflers have the four corner factory crimp. This exhaust is from my GNX #478. The exhaust has a little under 8K on it. I will email pictures for any serious buyers. Please let me know if you are interested with any offers - this is an original GNX exhaust. Thank you for your interest, I am in NJ.
