Daaaaaayyyyuuuummmmmmm I take it you don't have a silencer on it yet? And it's always good to head a 500 revved like an 80 or 250 LOL!!  Honestly though, I have yet to hear anyone really ring out a Zilla. Not even duners!! That put put it around till they get to a hill then go up it. That counts as ringing it out about as much as drag racing. IT DOESN'T!!! Lol (THAT'S NOT HATERAID, GUYS, CALM DOWN)

I can't wait to see you running that thing!! I'm kinda curious about how that pipe is gunna make it act though.  It looks more suited for a 125 dirt bike than for a 500 But hey,,,,,, never know!!!
