I am looking in to buying the Jet Kit and IDSII exhaust for my 2000 sportsman 500. I put on some 26 tires and would like to reclaim some power.. Would this help? Have you done it? If so was it noticeable and worth the $$$$$, Sound is ok but I want more power!!

 

I really like my FMF megamax II. It makes a lot more power than stock and is not very loud. For $170 you can't really go wrong. The 162.5 jet is what I run with 10 discs so you should be good there. I hear the K&N kit is a rip off and just sucks up your fuel mileage.
