I love the feel of the fatty and shorty on my YZ. Added bottom and added a little over rev. great combo for mx. Although in the wet/loose stuff the stock pipe seems to be a little better fit. No jetting change needed when I installed mine, still spot on! If you currently run the stock jetting odds are your a little rich on the bottom anyways (come rich from the factory) so the pipe/ silencer shouldnt require a jetting change for you.

I have a 09 yz 125, added a Factory Fatty and Ti 2 shorty, works great. This is the most noticible improvement I have done without going into the engine.
