KillerB, the real enthusiasts appreciate your work IMMENSELY


And normal 304 is still not up to the task of a turbocharger header. Maybe 304L, but that is $$$

So based on the reviews this would probably be a great header for a mild street/auto-x car with room for a stage 2 tuning?

Also seems like there's on uppipe on this should an HKS uppipe be used with it to get the most out of their "system"?

an uppipe is not really a required mod as your 08 uppipe is catless anyway.

and imo this header is good for anyting from mild to wild. a bhhamblin is running a stage 2 08 sti and it feels great on his car

Not sure if this was covered.

Will this fit with an undertray or is there a restriction/melting issue?

undertray is confirmed fit for 08+


06 undertray fitment is not know but likely to fit without issue. there would be more distance between the undertray would be and the header than there is with the fan shroud so i dont imagine an issue

How many miles on the header? You're the first person I've seen with this header installed. I bought one because of your review. This header does fit better than OEM ex manifold (had Grimmspeed ported manifold prior). As with any HKS or anything JDM that I've ever installed, they fit just as good as or better than OEM. I installed it last december and put over 1.5k miles while I was back in the states for vacation. The header looks well built and I like how the engine is smoother, quieter, and more powerful. Turbo response is incredible.

Wow! So my "inferior" 409 header isn't as likely to crack like all the other 304 SS in 3k miles. HKS designed a good header. This confirms my friend telling me that it doesn't really matter what type of stainless you use, but he did mention also just as long it does bear too much weight. All the other headers don't reinforce the collector like the HKS EL manifold.

It comes with a 'heat shield' according to rallysportdirect.. where does that attach to? Looks like a nice item for the price.

It attaches to the manifold between the main bend and the up pipe flange.

I am 99% sure I will be going with this header as well and ording in a few weeks.
The Killer B is a great part, but last I knew it isnt compatible with my Grimmspeed UpPipe and EWG set up so if the price wasnt enough to make me move away the EWG deal sealed it, I was looking at an InVidia but I'm thinking I am going to get the HKS as soon as i'm back from vacation in a few weeks and then send it off to get the white lightning ceramic coating and putting it on my 07 Limited. I need to read more though as I would prefer to keep an oil cooler.

Did you say the newer style one will work and that you just have to change the neck on the hose azn2nr? rather collect all my parts and do it all in one step and also swap my injectors out for e85 and retune

I am curious as to what exactly is the fitment issue on an 06-07 WRX. From the pictures, it looks like there is a good bit of room where the oil filter is. What would one have to do to make to work with the stock cooler (what's making contact)? Do the lines need rerouted? Are the metal inlet/outlets in the way? ???

The oil filter its self will hit the header, thus why the oil cooler will need to be removed. This is on 06-07 wrx since the oil cooler has an adapter on it that clocks it differently. It might still work 04+ STi

adapter....

Yes. The pictures in the first post show an adapter which offsets the cooler and puts it at a funny angle.

I'm really not quite sure how I can make it more clear.

And the STi cooler is straight then? What about the hose line fittings that you had mentioned?
