Still in production??? I've searched many different forums/websites and I've e-mailed them and never got a response. It seems like a nice piece. I'm also researching about the WeaponR 4-1 Cougar instead because a few places stock those at reasonable cost.
I know nothing about the ZXtuner header, but I do have the WR SS 4-1, which is very nice. The downstream O2 sensor was a tight fit, but no biggie.
i've got the zxtuner header on mine, it works well if you have alot of other mods but if you only have a few engine mods you get a very marginal gain in power for quite a bit of money IMHO.
your better off spending the money on getting a decent intake manifold on a zetec, that is the real restriction on power.
the standard exhaust manifold flows quite well if you remove all the EGR and pulse crap from it.
What intake mani??? You can't port the stock one right? Since it's plastic. Maybe a 2-piece Focus intake manifold? I can't see how my exhaust manifold flows decent especially with that huge cat converter attached to it with over 130k miles. Do the Mondeo's have a diffent manifold setup? I was over at the Cougar boards and a guy from overseas posted pics of his downpipe and it was totally different compared to the US spec. The cat was underneath the engine right before the flex pipe. If that matters
