I Just Bought A Ti Sti Shift Knob For My 06' Wrx. I Was Wondering How You Are Supposed To Seperate The Boot From The Old Knob Once You Unscrew It . Any Help Would Be Greatly Appreciated.

Yeah just hold the boot and pull the knob off..

Just pull the knob upwards while working the boot downwards. The stock knob has a flared ring that keeps the boot up.
