Header set won't be stock/OEM as it eliminates the cat on the Zetec.

WeaponR Cougar headers are stainless steel & can be found on Ebay. As always be careful who you deal with, pay a few extra bucks to buy from somebody with plenty of positive feedback. There are other brands out there for the Cougar, I think... Search ZX2racing.com or sup'm like that & you may find some other Cougar headers.

Must be that jumbly-wumbly thing happening again.
