S&S Cycle Diamondback 2-1 Exhaust System, Guardian Black with Black Endcap for 2017-'22 M8 Touring Models

Are you looking to add a little more sound and horsepower to your M8 powered machine? S&S designed this for you. S&S was building Performance Baggers long before it was called that and our focus has always been on making big power! The Diamondback two into one exhaust is a perfect example of their commitment to true performance. Beginning with a stepped header for maximum flow and a merged collector specifically engineered to prevent exhaust gas reversion, this system wraps up with a 4" full stainless muffler that ends before the rear axle. Diamondback is not for your Daddy's bagger, but purpose built to make big power and sound, excellent cornering clearance and just the right look. Clearance for tall shocks.


  • Super durable Guardian Black finish
  • Oversized stepped header primary tubes for optimal flow and performance
  • Header length helps your M-Eight motor make excellent power
  • 4" OD diameter stainless steel muffler ends before the rear axle
  • Four exhaust bungs for easy O2 sensor installation and air/fuel monitoring
  • Computer aided design & precision bending for improved ground clearance
  • Every S&S part is made in the USA

Note: Not legal for sale or use in California on any pollution controlled motor vehicles.
