2017ish M&K GT3 2/2 muffler, probably has 100 or miles of use. It's loud, light, drones in 2300-3000 range, and the craftsmanship is second to none. Selling because I just replaced it with M&K's new "street" version of the same muffler. Mods, please move to the "other parts" forum if not appropriate here.

$700 + actual shipping
