Well I bolted my Ti-4 up last night and did a comparison to the stock one, and the Procircuit was really awsome. I had much more throttle response and it reved way longer, if there is anyone out there ready to buy give this pipe a shot it works very well on the 05. :D :naughty: :naughty:

I have the T-4 (none ti version) on my 02 YZ426 and it works GREAT! The bike seems to "Bark" coming out of the corners much harder then with the stock pipe. :naughty:
