Just installed on Friday and rode yesterday, thanks to Allen and Rob Kroll one of the best tuners around period.
We have 2 identical MPI Nytro's. My dad's is geared at 23/39 and has the Hartman muffler and he has been beating me by at least 3-4 sleds. Mine has 24/39 gearing and stock exhaust until now. Robb installed exhaust and tuned the fuel in late friday to get me riding before we lost all of our snow.
The result was awesome as now these sleds are very close. My dad's still has a touch more in the mid and mine has a little more on top. Unless your are running 2000ft plus the 23/39 gearing is the way to go. I will be changing mine and then they should be very close as the clutching is the same. I do weigh about 30lbs more also.
I thought the exhaust performed very well, the sound is quiet at idle and low rpm's. When you open it up, look out it is very loud. I personally like it though!
