how hard to install shorty headers.

Its not really hard but very time consuming, personally me and my dad installed them with the k-member off as we were working on the suspension at the time.

For a natuarally aspirated car headers won't do much.

Ohh and one more thing, we got some JBA shorties, and if we were to do it again we would have gone with the longtubes, just something to think about :shrug:

there are some good instuctions http://fnsweet.com/garage/lt_install/index.shtml

good luck on what ever you do
