    Solid pipe, looks and feels durable out of the box. Pipe sounds great very aggressive, deep and throaty 4-stroke thump. Pretty tame at idle but twist the throttle its a beast. If you ride alot in town or noise sensitive areas may want to consider buying the quiet baffle insert for it but is manageable without it just don't get on it to hard. Only complaint like others have said it is a tight fit to get on because the bolt supplied by FMF is fairly short. I used another stainless bolt from my bolt bin same size just a few threads longer so the bolt will catch the threads on the u-clip on the pipe. Other than that it's a great pipe.

    Fit perfect on my sons bike. Between the exhaust, air box and jetting, his bike has defiantly woke up quite a bit. Sounds great without being too loud. Easy install. Gets really hot on the pipe itself, you need a heat shield I used the stock heat shield that I attached with conduit hangers from the hardware store.
