I installed the FMF universal turbine core 2 yesterday and I love it!I got the idea from boostcrzy and for 116 shipped you can't go wrong.I cut about 4 1/2-5"s off,tapped the midpipe on with a rubber mallet and slipped muffler on.Just use the supplied spacer for the mounting bolt and its done.I love the sound & look except the sticker,pulled it off and put one of the original stickers as I'm used to that sticker because my racing quads have all had it.Just need a jet kit,ordered one off eBay supposedly they make for your mod list.Ill post pics when I get to a computer.
