Perfect fit, nice, clean look, and sounds great. Not much for power gain but this is a small quad. Overall if you are looking for that trick look with factory race sound, this is it.

Put this on my Raptor 660. The only complaint I have is the strap that is used to fasten to ATV. I hate the way it looks and it seems like the rubber padding will eventually wear out with heat. I definitely like the pipes that have the welded bracket to attach to your model ATV.

I can feel the power gain from this slip on muffler. It sounds really good too.

My fmf power core 4 is great, very easy to install and sounds great. I put it on my 04 400ex and I am very happy with it... I would suggest this pipe to anyone

This pipe was put on a 06 raptor 350. I hoped for a little more growl and a little punch. You will get a little throatier growl, but not a lot if that is your thing. I put the pipe on for my father-in-law. He is a mechanic and said it probably wouldn't do much on his stock raptor. He jumped on to give it a go and the thing almost went right over. It was like night and day. Definitely worth purchasing as the first up-grade on any bike. Really impressive power upgrade!
