Make sure that pipe isn't touching the frame, you'll eat a hole straight through it.
Either put a dimple in it for clearance, or try to tweak it some for clearance.
The FMF that was on my 250 was the same way, and I had to patch weld it back together.
It slobbered sooty oil all over everything LOL

The zilla is not capable of lighting standard LED driving lights by itself, as there is no 12VDC supply.
You have a few options if you want LED's, however.
1. Buy an LED lightbar that was designed to run off AC currents (moderately expensive)
2. Run the LED's off a removable, rechargeable battery (night riding is limited to battery size and quantity, the bigger the capacity, the pricier they are)
3. Install a charging system (labor intensive, moderately expensive)

For the first option, the only one I know of is from baja designs www.bajadesigns.com, they build an LED lightbar specifically for ATV's running AC current (that's us!)
With the second two, you have the option of running HID's instead of LED's as well.
Also keep in mind that the stock charging system is only good for about 60-70 usable watts, unless you buy higher watt coils from Ricky Stator.
