Very true Sgt Marshal, and a valid thing to think about. I got them because they looked good, I intend on modifying it much much more, and because I was already replacing my catalytic converter and transmission at the time.

As far as installation, headers are really quite easy to install. I've been running a cheap ss high-flow catalytic converter with mine and replaced the cat, exhaust, and o2 sensors for under $300 including shipping and taxes. Took me about 2 hours to do even without a lift (though, I have done quite a bunch of mechanical work on these cars so take that with a grain of salt). If you're already taking off the crossover pipe and front header, you're already half-way there. Don't throw away your time or money in my opinion, get full headers.
