Welcome to the next generation of the Sportster. Lighter, faster, water-cooled and — sadly — very muted. Luckily, the performance gurus at S&S Cycle are already on the job and have recently launched a slip-on muffler that allows the most technically advanced Sportster ever created to sound more like, well, a Sportster. Designed to mesh with the factory header and shields, the S&S exhaust features its trademark removable decibel reducer that allows for easy sound and performance tuning. Wake up your Nightster with the Grand National Slip-on and look for more performance parts for Harley-Davidson’s latest from S&S Cycle. Like everything else S&S does, its exhausts are all made in the U.S. Check out the details here.
