Probably a 16 or 15.9. My guess, might be even slower

You Tube is your freind ^^^^^. Say Cole, I thought you weren't going to add a header? Also checkout Fwerks site too.

On a side note, I'm still getting used to the lowered stance. Ran over an effing asphalt boulder today and I would have cleared it except for the Stealth portion of my FSWerks exhaust. That kicked it up and it tore out some of my heat shield. Haven't gotten under there to really check it out but I foresee a trip to pick n pull soon.
Hey Josh, whats up? Does the fwerks flex work or not? Or the obx one? My foci is low too= no issues w/ the 6'' diameter stealth or the cfm 4 point lower stress bar which hangs down some= you can see it from the front. Not that noticable being semi flat black thou. It'd really be noticable if I painted red or orange or some bright color. The fwerks flex is $89. which is a lot of cash for a flex. They have you over a barrel huh? Seems like you need a couple of flanges & 2.5'' diameter flex hose, to make one up. I'll pm you Josh

Ok, I've read this thread through and still have some questions about the available headers. 1) do any of the available headers have 3 spots for my O2 sensors? if not what do i do with the extras? 2) What is the "tune" that you need to do after the header install?

Thanks
Steve

More about the exhaust/ O2 questions

Yup yup u need the exhaust done first . The "tune" is actually a Re programer. They range from 317.00 -375.00 depending where u get and you'll need 3 programs Basic, fuel economy , and Performance. And depending where u go a good shop will sell thosr for 8/ bucks a pop. Soo your already looking at 600 for computer to do the aftermarket stuff

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

^wow

If you want the best get a fsw header, any kind of stainless steal 2.5 inch exhaust and buy a programer from Tom at focus power or from randy at focus sport. You only need one o2 sensor.

Don't forget that any state (or country) that plugs into your OBD port during a smog check will see if you have any O2 detectors turned off. Get a header with 3 ports or have a shop add extra ports and do the mechanical engine light fix that you can find in the how to forum.
