S&S Cycle launched the GNX slip-on mufflers last year for the M8 touring bikes, and it looks like the twin-cam guys demanded them as well. S&S is finally adding twin-cam fitment to the rowdy GNX slip-on line. S&S says the GNX slip-ons are the cure for plugged-up pipes and are designed specifically to let your engine roar the true sounds of freedom. That's quite the statement; good thing S&S backs it up with a stainless steel louvered baffle that is specifically tuned for big flow and even bigger sound. Much like all of the S&S exhaust line, the GNX slip-ons also include a decibel reducer that lets you tune sound and performance. All this freedom and they still managed to come in at $569.95 per pair in black and $639.95 in gleaming chrome. Check out the GNX Slip-on on the site or hit up your local dealer for more info: www.sscycle.com/letfreedomfly.
