I have a 2007 800 Sportsman that is completely stock. I love it but want to get more bottom end out of it. I was thinking about doing a slip on exhaust and clutch kit to wake up the bottom end so it will wheelie more. Anybody have any good kits they would recommend? I’ve looked at full exhaust but its a bit expensive and you need to get a EFI controller. A lot of what I have read is that the slip ons don’t add any HP. That true? I have the single muffler.
