S&S CYCLE Grand National Slip-On Mufflers - Black - Race Only 4110-266-R

If you're chasing lap times on the track, exhaust flow and weight reduction are non-negotiable. The S&S Cycle Grand National Slip-On Mufflers deliver measurable performance gains while eliminating excess bulk from your V-Twin's rear end. The removable dB reducer lets you dial in sound levels for different venues—keeping you compliant at sanctioned events while unleashing full acoustic potential when conditions allow.

These are true bolt-on exhausts: no dyno tune required, no custom fabrication needed. Just unbolt the factory muffler, bolt these on, and gain cleaner lines, lighter weight, and the aggressive V-Twin tone that separates race-bred machines from street bikes.
