i have the pc ti4 on my 07. i love it.. fitmit was not an issue as the system took 10 mins to install. on the 07 it didnt make a drastic change to the low end as lets say a dr.d would but it woke the middle and top end up tremidously. it dosnt stop pulling. a great exhaust for the money..

Get the Pro Circuit. Here's a story: My friend just bought the Ti4 and ended up crashing and breaking the can. He sent it back to Pro Circuit and it took a little to get back. He called and they said that because of the inconvinience they sent him 2 Ti4 Pro Circuit for his 250f and one for his 450. And to top it off, the MItch Payton called back and apologized for the problem as well. THE MITCH PAYTON.:p His/our mechanic is also an authorized parts dealer so Im sure that kinda helped but that totally made my day.:lol:

Isn't Akrapovic the pipe that Factory Yamaha uses? If so, you know you cant go wrong with it.

If yamaha put a muffler off a lawnmower on their bikes would it be the best one to get?
