So I was looking around for a slip on exhaust for my Versys and found all the prices to be a tad high for the budget right now. Me being cheap (part Scottish) I found a custom alternative that fit the bill on www.kawasakiversys.com that was not too loud but a bit deeper than the sewing machine stock exhaust that came on the V. Total cost for me was around $50 since I had most of the clamps and strapping required for the job. I took about an hour of work once all the parts were gathered and a little tinkering after the fact. The weight savings is 7 lbs versus almost 20 lbs. So if you have a Versys, ER6-N or a Ninja 650R the following link will bolt right on with little effort. I guess there will be no more sneaking around after midnight picking up tags. Cheers.
Also, here is a YouTube link from the guy who posted the mod. Not my V but the sound is pretty spot on.
