Description
If you’re running an M8 and want genuine V-Twin character without committing to a full exhaust system, the S&S CYCLE GNX slip-on delivers a muscular, rowdier tone right out of the box. The louvered baffle design extracts authentic rumble even when paired with stock headpipes, giving you real performance gains and visual presence without the complexity of a complete system swap. Built to S&S Racing standards and made in the USA, these 4.5″ chrome mufflers combine premium fit and finish with genuine acoustic engineering.
