Question What's best extractors / exhaust for 3.9 mpi?

What are the best value for money extractors and exhaust system for an EA S pack 3.9mpi 5sp in (a) stock form and (b) with mild cam and maybe programmable or matched (Chiptorque) chip?

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.

This EA I know is getting Extrators put on it I hope they work for him
I am pretty sure they will give him ones that work good on his engine
how many more KW do extractors and exaust put out??

EBII 5spd , Redback 2.5",high flow cat ,Clear Indicators , Sony 50x4 with amp+sub.
Would people buy a commodore if it had a BTR-95le?
Would anyone be safe if the falcon had a THM700

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.......

EA Fairmont Ghia : 3.9L MPFI, 2.5" cat back sports exhaust, K&N panel filter. Pioneer head unit, pioneer 4" three way fronts, Pioneer 6" 3 way rears, 2x 12" subs, blue interior light.
My main pride and joy : '76 XB Fairmont GS, 250CI, 140,000 Km and all stock.... for now! (Factory air-con on the way)
