MOTHER OF GOD! For those of us who ride the 800's we all know and our friends we ride with know that the 800's sounds awful. I'm pretty sure that just changed. I took a chance and bought a GSE performance muffler from eBay. This thing is pretty wicked. It has dual 1 1/2 inch outlets coming straight out the back and it's a slip on. When I fired up my 4wheeler for the first time after installing it I could not believe it was the same quad. The tone is low and grumbly, it is considerably louder but now we can shut the Can Am guys up, and while I haven't ridden in the woods with it or anything as of yet, the angry weed whacker seems to have disappeared! I didn't take a video yet because I'm sure the neighbors would call the cops on me if I went barreling down the alley at 11 at night but I will get some video to post in the next couple of days.
