9 times out of 10 the stock can on any sled is the best tuned can available to purchase for that machine. You can dyno can after can, you will probably not find one that will gain any HP over stock. I, like you though, do not like the sound of most newer stock sleds. But, I have yet to hear of a can that's halfway between an SLP and a Sno Stuff that is more of a deep throaty sound then the good ole "pingy" Sno-Stuff that still isn't too loud. I wish Poo still made silencers the way they did with the 98-99 XC 700's. Good deep loud grumble down low, not much louder than others on the top end to annoy any land owners.
