I am looking at getting a Leo Vince x3 system for my '05 yz450f. Has anyone tried it? What did you think of it (form, fit, function). I currently have the stock head pipe (custom bent with a big rock) w/ a '03 yz/wr 450 Pro Series t-4 can and pipe. I'm not very impressed with the PS but it has a spark arrestor and I got it for $100. I usually ride woods, tight trails; but also alot of fast stuff. I can't seem to find any info on how this setup works on the yz450f, so any help would be appreciated. Also what kind of pipe guard would offer the best protection?
