Oookaaaaay... There won't be a Pulse Charger pipe for this bike, so I won't be testing that out. The limits of my testing with that were getting dyno runs of all the different configurations; Stealth, Race, and Unlimited. Great pipe, no longer in production due to BS legal battles. Sorry.What that quad really needs is the Pulse Charger then that think would really be awesome. Hopefully Normalz will be the first with a pulse charger exhaust. The last GNC race I was at I was telling all the pros about the pulse charger and that they needed it. They all kind of laughed a little bit but then I told them about the z400,lt-r, and kfx450central.com's and to seek out Normalz because he's done some extensive testing in the past. Normalz, when are we going to see the dyno results on this quad with the best aftermarket pipe on the market? I can't wait!!!
