FMF Muffler, with Gnarly. It`s not fit as the Fatty, but easy to install it. This is a 2nd one, the first one wasn`t fit, so I was ordering another one.
I wasn`t lucky with this one, I had to send it back the first one, it wasn`t fit on my KTM. This one kind of okay, but not perfect. I mean it was harder to install.Fatty is perfect fit, this Gnarly just fit.
I really don`t know, I guess it`s for bottom end. If you want top end, you should buy fatty. But as I say, I don't know because I've never measured it with a gauge, but it seems to be better at the bottom. Also, cheaper than the OEM.
