This could be a concern if you run the big superhighway type trails at big speeds for extended periods...I certainly don't see this as an issue in my tight trail system.

What foam under the muffler are you speaking of? Mine had no foam anywhere near the bottom of muffler. I do remember TD saying to not put the heat wrap that goes around a stock muffler back in there if you were putting shields on a none stock muffler.Ill be honest...I haven’t heard or seen anybody unhappy with their SM Tunes from any Vendor! I don’t know where this negative talk idea is coming from? Maybe before they were released, there was some concern from some, but after a year on the snow, these have been Absolutely superb.
And after installing mine, and taking the foam out from underneath the muffler...mine seems cooler than stock. When I ran the stock tune the first year, I could really feel my right boot heating up from the heat of the muffler. Last year, after removing the foam and installing the SM Tunes...zero heat on my right boot. So go figure?? Was it the foam holding more heat in there? Could have been?? No issues whatsoever.
Do yourself a favor, if you’re on the fense about SM Tunes..don’t be. It’s all good and All GO!

Mine had foam under the muffler that needed to be removed. It’s for sound deadening I believe from the factory.

Hi wolf,i cant remember that foam you speak about,but it could be that my sled was tuned from day one,and it was in pieces from day 9 when it hit a tree in my yard,and had to rebuild it from scratch,on my buck.Mine had foam under the muffler that needed to be removed. It’s for sound deadening I believe from the factory.

Im sure it was there Beast...mines an 18, so unless the 17’s didn’t come with it? But I’m thinking they must have.
