"Best" would be subject to you needs/requirements. Nobody has tested them all on one car, on one dyno, etc. so there isn't a really cut and dry answer. There is a lot of speculation out there, however.
Kudos to focus sport!!I agree..go with the focus sport headers that's what I'm running on my 04 duratec 2.3l..hommie said:I say go with the Focus Sport. They make some great products everything I own of there's is top notch! Not to mention the customer service is one of the best around.

CTZX3 said:I am leaning toward the F2 header, due to the Price, SS, Coated and the lenght also the primaries looks like they will work best.
So the F2 header is stainless AND coated? Made in the USA? Includes a flex? Something doesn't sound right. I'd guess the header is not completely stainless, the flanges are probably steel. Coating a high grade stainless header doesn't make any financial sense if you are selling it for $285.CTZX3 said:I 've had a OBX on my old Zetec Focus and its a cheap SS it WILL rust!
