For sale is a pair of borla stinger (s-type mufflers). These are 2-1/2 inch inlet/outlet. I purchased these used, they were installed for less than a day and traded out for other mufflers. I purchased these for my mach 1, but decided to purchase a full cat back instead. I'm looking for $250 shipped (In the 48 states) for the pair. Please hit me up by phone for the fastest response. (970) 903-4433. Thank you!
