I have an 04 ski-doo summit 800 and I want to put an after market pipe and silencer on my sled. So many companies/opinions. I want less weight/more hp/easy upgrade/decent price.I am not to mechanicaly inclined,so I would want something that required no/minimal engine mods. Easiest,best outcome. I can see how changing things can open up a whole more can of worms and more $$$. Is it possible to do this and what companies should I go to for it. Any info/advice would be great.
