I am looking into getting a slip on exhaust for my sportsman 550 EFI. I am looking for something that is made for mudding/ swamp style. I don't want something quiet. I want it to sound tough. Something that adds horse power but does void my factory warranty. I was looking at HMF swamp XL. Does anyone know anything about that slip on???

I have the big gun slip on on my 12' 550 and it sounds mean. I'm not sure about warranty but I like the sound. YouTube big gun exhaust on polaris 550 xp.

Anyone ever has the HFM swamp XL slip on exhaust??? Comments.... I have a sportsman 550 2013. Thinking about getting it

I just put the HMF swamp XL, sounds awesome only thing is if you're running a KN or aftermarket filter you need the optimizer to fix the fuel. Mine starts and stalls every once and awhile.
But amazing exhaust.

I have the swamp XL, and while it does sound better than stock, it's still a Polaris and still sounds like a bumble bee, although now he just sounds a little pissed off.

^^^ the XP motors sound different.

How much is an optimizer and who makes a good one??

HMF. If you are getting their exhaust, get the fuel controller that goes with it. Maybe they'll even cut you deal if you order both. It's about $370 for the slip on and another $290 for the optimizer.
