Git-R-DONE!
I did mine and I'm about as sharp as a beachball. Just take your time. I did mine in 5 days.
Day 1 - Unbolted the exhaust from bike. This is probably the most difficult thing to do because of the PAIR being in the way.
Day 2 - Got the pipe out from under bike.
Day 3 - Assembled new pipe and removed airbox from bike.
Day 4 - Did the airbox mod and installed onto bike.
Day 5 - Installed new pipe.
It can all be done in one day but I chose to do it that way as to not overwhelm myself, tire myself out, or get frustrated.
I plan on swapping out my swingarm using the same approach. This, by the way, was done on the Gen-1. I have no clue how hard it'll be for the Gen-2 but as mentioned above, it should be nothing more than nuts and bolts.
Good luck
