The boots are not regular boots to remove.

HelloCustomer no they are not there is a metal sleeve around them and they will come off if you can twist and turn them while pulling, but there is no way around it, they are difficult. Sometimes I use a prybar and pry on the end of the metal sleeve with the pry bar against the exhaust manifold. I wish it were easy but these are difficult, sometimes if you have special plyers you can hold onto the sleeve with the plyer and pry against the pliers as well.
