not too bad to do.
First thing you want to do is jack the car up and put it on some stands.
Get under the car and take the plastics off.
Unbolt the Header from the exhaust at the bottom.
Unbolt from the engine underneath the car.
Unbolt the header from the 4port side.
Unbolt the heat shields from eachother.
Monuver the header around untill you are able to remove them from the car.
The hard part will be getting the stock header out of the car. I found that it was easiest to remove it if you flip it over while still in the car. Then just monuver it around untill you can get it free.
Will the aftermarket one it will just slide in because there is no engine mount on it. (Make sure the donut gasket is already on the header all the way)
Then bolt the header up on the engine side.
Then bolt the header up underneath the car.
