OK, any more info? Thoughts of the header, power increase? Don't leave us hanging here lol

First things first I pulled the o2 sensors and had shield. Four heat shield bolts, 10mm.

O2 sensors were 21mm.

No pictures for this part. I went under the car and removed the mount for the stock flex pipe because my header does not have a place to mount. I also disconnected the cat back and pulled off a metal plate and exhaust hanger just before the rear axle to let the cat back rest on the ground.

I then pulled the bolt that held the transaxle to the RMM.

Now I pulled the header off. To get it to fit out I had to drop the engine a bit by disconnecting the passenger motor mount and pulling the middle stud for the header. Lowered engine with a jack and after a few cute words it was out.

Also had to take the plate out from under the black trim below the windshield before header would clear.

 

[Whodatxevg]

After the old header was out the new one went right in without a problem.

Now everyone told me that the o2 sensor is too short and I need to buy the Porsche one, but my car is currently running on the stock o2. I took the sensor connector off of the bracket on the valve cover and rerouted the wire and then it reached with enough slack for engine torque.

In for results

No dyno but car seems to pull quite a bit harder from 3500-7200. Below that it feels the same.

Engine sound through stock exhaust is slightly louder. Not loud enough that it sounds aftermarket but you can hear it.

And then obviously install is the reverse order of dissasembly.

Nice job man. Congrats on the new header and hopefully 14's to come. You can jump on the dyno free if you head south to this focus gathering/cookout. It should be a good turnout. http://www.focusfanatics.com/forum/showthread.php?t=499825

In for results and sound clips?

 

[Whodatxevg]

@Juicedz, damn I can't make that day. I'll be leaving Florida on the 28th.

I'm going to risk sounding stupid here.. But is there a header on the market that will pass emissions? (Not CA)

 

[_RED_]

Unfortunately no, since all of them remove the factory catalytic converter. None would pass CA smog.

 

[Mr.N00bLaR]

I believe you can pass with just one (aftermarket too) cat where I live in NY. Its tempting to buy a header and have a shop weld a cat in some where for a full legalish exhaust.I'll have to see how much the sound increases with the ST CBE before I consider anything else though.

 

[Whodatxevg]

Here's my time slips from last night. Seems I picked up 1-2 MPH and about .2 in the 1/4 mile.

Is there a engine light or do you have a tune. At other things you do to make this work?
