How hard is it to install headers? Is it possible for me to do it by myself when I buy a TA?

yes its not that bad to do it your self.. it just takes some time especially if your a new at it.. but its really no big deal.

It is hard enough from what I've seen/heard but not impossible, some headers are easier than others.
If you have a lift or at least the ability to jack the car up REAL high then you and a friend can do it if you follow the helpful hints shown elsewhere on this (and other) site.
