Hi!! I wanna say thx for the idea, im in the process to do the same principe :



But a friend of mine say this setup could push unwanted exhaust of cyl 2 in the 4?

If you check the pincipe that the subaru the firing order is Not the same but the cyl of the others runner on the headers is closed.

The way we do it look like we gonna send unwanted pressure on valve....?


Sorry for my crapy english, im not bilingual, lol


Have a Nice day every 1

 

Well like I have said before, I have not noticed any issues with mine so far. When I was first researching this setup, I made sure to match the cylinder firing orders just like a subaru does. There shouldnt be any reversion pressure going to any valves

 

Well thx!
But if you look carefully the firing order of the subaru prevent réversion because all piston are close on the same side but with our headers design, the pattern look risky, well i dont think the exhaust pressure gonna be enough to push the valve but i did my homework even if you compare the firing order of a h4 vs i4, the piston dont move the same way,
well mine is almost finish, gonna wrap it, have seen a noticeable sound change?
Have video or pictures installed?

 

No news about thus Guy?
Well this is mine, powdercoated. Gonna Dei wrap it too next week.

 

skip the wrap, not worth it

 

Review your fact and opinion, wrap wort it for keep temp lower in engine bay....

 

Wraps hold moisture and will cause your header to rust out.

It really isn't worth it. Even if your header is coated.

 

Where's the vid?

 

 

You might want to consider skipping the wrap though.
Powdercoat already does a going job of dealing with temps.

But if you got the money then
It's not like you paid $600 for your header + wrap looks awesome!
My bet is that you will be well on your way into a different project before you have any issues.

 

Well a 40$ header wrap aint going to ruin me haha, then i prefeer the wraped look who gonna remove the bad weld look too.

And if you see, i put all the bend for the wrap/mounting bolt and powersteering /alternator space ready.

 

For the leak, use water

Here mine wraped

 

DragonEye has successfully hijacked F22's thread.
It is now a race to see who posts a video first.

 

That was not for taking control of the thread, i just wanna add some informations and some pictures for people who want some

I can just remove them if "f22" are mad about it.

I already have a vidéo and a pictures on my h23a, but w8 another day to start a brand new thread. Thx

 

O_o I was kidding.

I don't think F22 is mad.
Would like to hear these headers soon!
>Shuts up and waits patiently for videos

 

I personally didnt care at all that this content was in my thread. Thought it was great having another one being made. Cant wait to hear it.

 

Still waiting on your video...

nobody cares about your exhaust leak when your video should be about the sound coming out of your muffler lol
