I have a 2000 Polaris 500 XC SP. Basically you could say I want to soupe it up so I can keep up with the 600's. It does about 95ish. Last year I put plastic skiis on it n it made it a bit lighter. Notice it was easier to skip water. I have been told to get a can on it, but with this increase performance? or just make it sound "cool" Also, was told to get an exhaust package...does this come with the pipe and can together?....also told to get a clutch kit...mess with the ratio...but i dont just want to increase acceleration n decrease top speed..or vise versa increase top speed but decrease acceleration...........is boring it out worth it? this decrease gas milliage by a lot? will my engine be able to withstand that compressoion?........anything i can do to it to make it lighter?...i would love to make the thing lighter.......I picked up for cheap only a grand...no scratches or cracks..brand new track thumb warmers all ready to go...so i dont mind throwing in 500 or more in parts.....
