Our line of MK45 touring slip-ons gets a third tip design with the addition of the new Cutlass. Perfectly angled to match your bags or reversible for a slash-down look, the Cutlass tips are powder coated using a heat-resistant gloss black. Like all of the S&S Mk45s, this 4.5” muffler includes our removable dB Reducers that allow you to tune for sound and backpressure. Available in Guardian Black (a dead match to the factory header) or show chrome finish for 2017-2022 Touring models. Look for the Twin Cam version in late spring. The Mk45 uses a RaceTEX packing for a low, throaty rumble that wakes up the sound of the bike without creating a droning note on the highway.
