Word! x2^^^

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!

Every long tube header is an improvement over stock. Other than that it's build quality, durability, fit/finish and personal preference.


Yup, I totally agree

02ztsian 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.

VinnyB 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.

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.


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?

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