You did get a killer deal on that thing then. My dealer wouldn't go under $6999 for a 2007 just a couple months ago, but they don't have any local competition so they get away with whatever they want to rob you for.
I don't care though, to me the 700 is definitely worth it.
Your 250 must be really built because I've only been beat in a straight line one time with my 700, and that was against a built ltr450 on the track. My warrior was actually pretty close to my cousin's stock 86 quadracer, and the warrior is sure as hell nothing close to the raptor.
What made you decide to go with the fmf quiet exhaust? After my first experience I don't think i'll ever put another FMF product on anything I own as long as I live. To me duals are the only way to go on the 700 if you're going full afermarket.
