I have for sale a Yosh slip-on exhaust for the 08+ Ninja 250. It is unused ( NEW ), the bike being started only 3 times. Comes with the additional baffle. Also have a stock header that has had the honeycomb baffle removed. Pipe was cut, baffle removed, then welded together ( NOT by me!) Sound is deep and melodic.
$300 for the slip-on, $30 for the header, PLUS shipping. Prefer to sell together. PM is best.
