Thanks for being the one to try this. Do you have the part numbers for the header and the flex pipe?

And I know from another thread there seems to be some confusion about whether PZEV or any other Foci have different cats

yeah there is no way that will pass in california, no cat is illegal at the fedreal level, but unless the car was impounded for some other reason they would never know.

That being said in some states, not cali, an aftermarket hi-flow cat would be enough to be legal, though you would lose most of the benefit of the new headers.

@focusboy
Are you going to dyno soon? thanks for testing this out first.

Yes I will shortly after I get some copper core spark plugs and gap them. Also have to put my Intake back on. Thinking about actually getting the AEM Cold air intake to compare to the K&N Cold air Ive been testing.

I usually only argue on things i know im 100% right about lol.

Which is why I seem like such a dick!

Also anyone looking to get this very soon Its a Duratec Fswerks header. Contact Fswerks to find out which flex pipe is the longest one and order it with that.

Or you can wait for them to officially announce it which could take months from now when they can test fit one. (OR maybe I just made them speed up the test fitting process so they can start making money off of these)

Nicely done FocusBoy58! Appreciate you being the guinea pig for this.

Interested to see what numbers you put down, and even more interested to see what numbers people get after adding a cat and what tuning can do for us.
