High-flow cat for Zetec - The Ford Focus Forum

**Lancer211** · 07-29-2009, 01:08 PM

I'm looking for a high-flow cat for a 2004 Zetec, but according to your site, the Magnaflow you have listed will only work with a 00-02 Zetec. Help?

Magnaflow only offers them for the 00-02 model years.

The focussport race header fits 00-04 ford focus zetec. Someone would think the magnaflow high flow cat pipe would fit 00-04 zetec also, but we are not sure about that.

I am not sure what changes in the exhaust occured in the 03-04 model years for magnaflow to say 00-02 zetec only.

Drat. Do you have any suggestions as to where I might be able to find a HFC for an '04?

The cat monitor sensor is inside the cat on '00-early '02 Zetecs, rather than after it.

So, Casey, what you're saying, (I hope) is that I shouldn't suffer any ill fx from CFM's Magnaflow HFC?

I'm not sure. I also don't know why there is a different version for automatics. If anything, the only real problem you might have is the O2 sensor wiring not reaching your harness.

Hmmm.... sounds like it's not a big deal. I can get Randy to tune that out anyway. Additionally, I would expect that it means that there's extra wiring in the harness, rather than too little. Of course, I don't know for sure.
