Greetings from DownUnder New Zealand.
I am building a FFR Mk4 using a 2004 4.6L Terminator donor and need to purchase or build /modify a set of headers but I am having difficulty locating a suitable supplier/ manufacturer. I was supplied with a Coyote set of headers in error and have just realised they will not fit. Any help, guidance & support greatly appreciated.
The name of a manufacturer/ supplier and part number would be great.

Here is a link talking about headers for the 4.6L DOHC. They are suggesting that the coyote headers will work if you change the flange to one for the 4.6L. Do a search on builders using the terminator engine, others have used the engine before, so someone has a solution.

Many thanks Alan_C, it all appears much clearer now & I will follow up with manufacturer(y)

I have a pair I'll sell for cheap to help you out but I'm based in the US and assuming shipping would be absurd.

Did you get this resolved? The stock manifold turned around with cats is what I used. It can handle the power just as well as headers. Here is a discussion from Svt performance that is a great resource for the terminator motor and every possible mod. Tubed Headers vs. Cast Iron Manifolds - Any H.P. gains?...... Also, if you are not running AC, then you can remove the AC and put the alternator there with a fabricated bracket. This is a good idea as then you can have the alternator on the accessory pulley and don't have to worry about issues that come up with your alternator on the supercharger pulley.

Did you get this header issue resolved? I have a set of the 4.6 DOHC headers which are aluminized ceramic coated and never used. Like Chris above, I am in the US and shipping is the question that comes to mind. I will sell these to you for $100US plus shipping if you are interested.
