It's actually pretty simple. I installed my Kooks headers without any real problem, just a few minor hang-ups from time to time. It's easy to do, but here's a list of concerns:

1. Make sure you can get the car high enough in the air. I had to buy a new jack to get it high enough. (Standard jack-stands work once it's in the air). Need about 2 feet of clearance under the front.

2. Be careful of the spark plugs! Some folks have damaged their plugs while putting the headers into place.

3. A buddy's help will save some time when feeding the headers from the bottom of the car and to move them in the exact right position while you're bolting them into the heads.

4. A bunch of people (including myself) have had problems removing one or more of the oxygen sensors. Some have been cross-threaded/bonded/etc. from the factory and are very difficult to get out, but it can be done with patience...just don't break anything.

5. I'm not sure about any other brands, but the Kooks 1 7/8" I installed did NOT need the steering shaft to be messed with, and was a very easy fit.

I'm not the most mechanically inclined person and have only basic to intermediate skills when it comes to working on cars, but I was very surprised at how easy the header installation was. You can do it, and save a couple bills by doing it.
