Yes the frame got the support after my95. As for the exhaust I have read too open exhaust might cause XT run too lean and it makes it run too hot ? Anyway I like to be quiet on trails since it's ..not very legal in most of the Europe yet a bit more oomph is nice especially on the second gear . Or I'll try non stock eg. Different from 15/45 secondary gears yet I would like to keep 100 kmh crusing speed so I might buy just s slightly larger secondary .
