4 months old. It's the trail series so not obnoxiously loud. I liked it but wife didn't so went back to stock, we ride for 3-4 hours at a time and she can't stand it after an hour. Paid $450 with shipping. Has spark arrestor installed comes with the clamp. Has some scuffs on it no holes. No need for tuner. Selling for $240 and I'll pay the shipping in the lower 48 states , pm me if interested. Also listed on ebay, thanks
