Hi EA S,

I've heard that 3-2-1 style extractors work well on these engines - ie. Genie put out a set like that.

That's hearsay of course - what I can tell you for sure is that my 2-3-1 set DON'T work!! (I'll be having a set of 3-2-1's put on in a couple of months).

If you can possibly manage it, try and find someone who's had definite success with a specific setup and copy that - with any luck just such a person will post here.

The HM Headers extractors and 2.5" system adds about 9% power i think. I am looking at getting a set for my ea. They claimed that i would get about a 15 rwkw gain. I got a quote of about $1500 fitted from an exhaust shop and about $1000 or so from ford not fitted. The extractors are stainless so i think it's good value for money. I'll let everyone know when i have them fited the difference it makes.......
