i never thought i would need awhole new slipper system i mean it's only going 8mph faster, and you think the 9L shaft would snap,, i could see stronger motors snapping but a 9L? and why would i need to buy the cable if i'll never need it? i'm full of more questions then when i started :W:
to clairify i want to know what gearing people use with the 9L, and whay gearing i'd need to go as fast as a stock e-maxx

You can gear down to make it slower. However, with brushless systems if you gear down too much you may end up with excessive motor heat from the motor spinning at top RPM much of the time. The safest way to approach it is to change only one tooth at a time, checking temps as you go, until you get to a good speed and temp combo.
You don't "need" a whole new slipper system. There are many people who run the stock E-Maxx slipper system with more powerful systems than you're looking at. Then again, there are many people who melt spurs every run in the stock slipper system. The choice is really yours, and I would use the stock until it no longer works for your application.
As far as the 1/8" shaft snapping, that is a combination of torque and vehicle weight. On 12 to 14 cells, a standard 1/8" shaft
should hold up forever, especially if you keep your truck under 11 pounds. A heavier vehicle with a more powerful motor would have a much greater chance of snapping the shaft, but it's pretty unlikely that a 9L on 12-14 cells in a 9-11lb truck is going to have problems with a 1/8" motor shaft. No guarantees, but you shouldn't have a problem if you're sticking near stock E-Maxx speeds.
