Akrapovic Carbon Fiber Slip-On for GSXR 600 or GSXR 750 2011-2017 Only selling because I have decided to start tracking my GSXR. As a result, I don't want to risk a $700 pipe, and I have reinstalled the stocker. This pipe is flawless, even comes with OEM instructions and box. https://lexington.craigslist.org/mpo/d/akrapovic-carbon-fiber-slip/6677337174.html
