I'm rerouting a stealth muffler (through an electric cutout) next to the MBRP resonator I had put on in my early 20's... The only way I can continue to own this car as I age is to be able to shut that bumble bee up!
The first header I had on there was the Focus Central 4-2-1; which eventually had welds come apart and leaned the engine to detonation. By the time the engine "windowed" itself, FC changed names and finding a direct replacement became difficult. So the eBay special ended up on my ride. That was in 2004 and the header is still in great shape!

|zetecDon||This is the FocusSport race header. I have had this header before. It removes your catalytic converter and makes it loud as Hell so prepare yourself for the obscene noise you are going to make lol. The loudness isn't so bad once you turn up the radio loud enough, but that droning on long distance trips will drive you insane.|

Yup, I totally agree

IMHO, there's no noticeable difference for the average Focus owner.
Any gains/losses will be seen with more and more power and RPM. I'd almost go so far as to say that below 7,000RPM and/or 160whp you won't see any difference.
Every long tube header is an improvement over stock. Other than that it's build quality, durability, fit/finish and personal preference.

If you go with the 4-2-1 header make sure that it pairs 1 with 4 and 2 with 3 like this one...
to properly scavenge the exhaust pulses.
I can't remember where I read this but the 4-1 design is supposed to be a high rpm header.

Hmm.. ok, general consensus is that it may be an FS Werks 4-1 header. Now, my other question is this:
Is there any noticeable performance differences from a 4-1 header, vs a 4-2-1 header? (The only difference I'm aware of is the design - 4 pipes in to 1 vs 4 pipes into 2 into 1)

|iminhell||x3, FSW header.|

Which link? The FF BST one?
Regarding the OBX, did you notice any performance gains? If so, how much? I'm not sure if I should buy piece by piece, or wait untill I have enough to get the entire setup at once. (header + exhaust)
Here's the OBX one: http://www.ebay.com/itm/OBX-4-2-1-Ex.../190755989627?

Pretty sure it is a FSWerks if you look at the picture.
Also the link you have is for a Duratec header.
And as far as OBX I had one for a while-a 4-2-1 SS header. No issues with fitment or welds breaking. I think OBX is probably among the best of the China-sourced headers you will find.

|JFrye||That looks a lot like my FSWerks 4 to 1 header.|
