Big gun exhaust on 2012 850 XP

What do you guys think of the big gun exhaust? I found a couple of you tube vids and the sound is awesome!! Do you need a fuel controller if you get a pipe?

the big gun is a great sounding exhaust. if you go with the full system you will need a programmer. if you get just the slip on there is no need for one.
