I have and 07 outlander 500xt an I don't know if it's just me or do these things shift really notchy I had a polarus previously and I miss the way it shifts. Also Iam wanting to install and hmf slip on and need to know if I should get a fuel optimizer along with the slip on exhaust.

Can am have a hard shift just rock the quad back and forth. As for the slip on you don't need fuel optimizer. My dear said the slip on don't really do anything but change sound. If your wanting a power gain you need to do a full exhaust then you will need a optimizer

^That's not right. You're changing the core size of the exhaust and reducing restriction considerably by putting a slip on. You'll only get an extra 0.5-1 hp extra out of the full exhaust compared to the slip on. You'll be changing air fuel ratio with the new exhaust so that should be adjusted. It may seem ok without a tuner but you aren't getting anything out of the exhaust performance wise if you can't add fuel.

I'm just telling you what I was told by the dealer.

Oh yea no worries. Didn't mean to come off rude. Dealers will say that the bike is fine without a tuner because the AFR may change to a new ratio that is still "acceptable" for running safely but it surely isn't optimal for performance.

I've noticed most dealers don't have a clue. Slip ons need tuners just as much as full exhausts.
