Remove the stock sway bar by putting the 14mm wrench over the bottom endlink bolt and put the allen wrench into the bolt.
Slide the rear bushings onto the bar and then mount the bar to the endlinks. Do not tighten them down, attach the hardware very loose.
Install the two bushings and hand tighten everything so that everything is even and equal. Do not tighten the rear bushings too much, you can strip out to bolts.
Tighten everything down and check the install after a few hundred miles or if you hear any noise.
Remove the front endlinks by using the 14mm quick wrench and the 6mm allen wrench, just like you did on the front.
Remove the bolts holding the cat to the header using the 12mm socket and the 6" extension. Remove the sway bar by pulling down on the cat and wiggling it out.
Tip: If you have an air ratchet, it will speed up this step quite a bit and make it a lot easier on you.
Install the endlinks using two 14mm wrenches. Install the sway bar similar to how you removed the stock bar. Losely attach the sway bar to the endlinks and install the bushings. Tighten everything down and reinstall the cat to the header and reconnect the first O2 sensor.
