Electronic muffler, "Project" type. A nice muffler with a musical, not annoying, tone. The muffler is new, used for (only two weeks). The muffler is without the control unit. The control unit with the remote costs no more than 200. Used for only two weeks, no more. It hasn't been tampered with or played with. It's new and guaranteed. And for the serious buyer, we won't disagree.
