most focuses have 3 o2 sensor ports. if I was you I would not go withthe FSWerk. that header for the 4 into 1 which is the same as yur stock headers. to get more performance out of your exhaust you have to have back pressure. going with the weapon r goes from 4-2-1 the weapon r has 3 o2 ports 2 up top and 1 at the bottom down next to the flex.flexpipe. either way because you have to have every programmer so program your computer in your car so your computer does not registered airflo wrong whether u have 2 o2s or 3. And the "tune" is to change the way the computer thinks and to do that u need that re programer. And what u do is plug it it and make ur computer not register the o2s that way you can have your up grade and not have problems with your service light
