I looked in a search and I could not find what I was looking for.

Where do you guys recommend getting headers? I am looking for my 94 Cougar with the 4.6. Thanks for the help!

your choices are VERY limited, supercoupeperformance sells kooks mid length headers, which are the only good headers available but expensive, theres also jba shorties but they have issues and dont provide much gain.

the stock manifolds can be ported to flow very well also, and wont cost nearly as much as the other choices;)

is it even a noticable gain?
No.At least not with JBA's.Maybe there was a gain but I never felt it.Who knows.If I had to do it all over again I would go for the Kooks right away.

On modified N/A 2V's, the Kooks are worth about 15 - 20 RWHP.

The JBA's issues were fixed apparently. And I must say that there quality is very good too from the ones I have. As for gains, I’m sure kooks would be more. Tests with mustang manifolds vs. shorty headers (ford racing) showed almost no gain on the dyno. BUT the mn-12 manifolds are more restrictive then the mustangs.

kooks are the way to go.... but so expensive... :( coated headers, dead soft gaskets, long o2 sensors, adapters, adapter gaskets, probably time for new cats, stage 8 locking fasteners, than the actual task of installing them, and than the cost of a shop to do exhaust from the new cats back, money adds up quick

I've got a set of Kooks, but haven't gotten around to installing them yet (I'm lazy) Got any suggestions on brands of gaskets/bolts? also, what do you mean by "Long 02 sensors"? Just longer wires? or am I missing something?

Ryan - When I got O2 sensors for the 91, I had the option whether to get long or short wires. I went with the longer wires to be on the safe side :D You can always tuck the wire somewhere, but it's harder to make it longer.

Percy dead soft gaskets, stage 8 locking header bolts for the 4.6/5.4 ford modular motor, both availible on summitracing.com, those are the only way to go, you don't want an exhaust leak or to have to tighten them a few years from now because the bolts backed out do you?

are the coated ones a must? or can you just buy the uncoated and spray paint them with some high temp paint?

i bought the uncoated ones as i am totally broke and even buying them was a stretch. as for the bolts and gaskets, you dont need any parts for them b/c the person making your exhaust should have them.
