For sale is a set of 4" Rinehart Slip-On Exhaust in Chrome with the black end caps part number 500-0106 for 2017 and up M8 Touring bikes. . I had these on my bike for about 500 miles, they sound awesome but decided I need the black version inside of chrome, I paid $649.00 for these, you can have them for $395.00 shipped. There are some fine marks from where I installed the factory heatshields on them that can probably be buffed out with a buffing wheel or just install your stock heatshields.
