Common questions
Will these slip-ons fit my 2012 or newer Dyna?
No, these Cobra Speedster Slashdown mufflers are specifically designed for 2006-2011 Dyna models. Later year Dynas use different header configurations.
Do I need a fuel tuner after installing these slip-ons?
Slip-on mufflers alone typically do not require remapping. However, if you have other performance modifications, a fuel tuner may help optimize your bike's performance.
Are these mufflers difficult to install?
Installation is a direct bolt-on process onto your existing stock headers, making it a relatively simple upgrade for most riders.
