Header install question.

[Zackjoe15]

Im trying to put an OBX header on my buddies 09 rabbit but cant find the torque specs on the nuts to go back on the stock studs. Does anyone know? I have searched everywhere I can think of.

[TylerO28]

You're going to need longer studs fyi. So get those first. Then tighten until snug. Lol I actually used some loc tite. Let it dry then put them in. it keeps them from backing out, but allows removal if needed

[Zackjoe15]

Thanks just wanted to be sure that would be enough. Where can i get longer studs and are they hard to put in?

[TylerO28]

You need to find a place that has metric studs. I think its 8x1.0 studs get 35mm length so you have extra length. To pull them out, you'll need to lock one nut onto the other nut.then UN screw the stud. So put one nut on, then screw on another. hold the first nut in place with a wrench and tighten the 2nd nut down onto the first. Then remove the stud by loosening the first nut. Arp makes Nice ones with a hex head but they cost a lot. Like around 120 for a set. Look online for extended exhaust manifold studs.or 35mm VW manifold studs. Its honestly a huge pain.during My turbo install it took more time removing those bad boys than most Of the installation

Thabks for the help. Wasnt expecting that just putting an OBX header on was gonna be so damn complicated!

[wingtsang]

I have the obx header too, not only the nuts you have to change, and you have to custom the mid-pipe too, good luck

[thygreyt]

you are going to need a new exhaust gasket, longer studs and a recommended new nuts.

coat everything with antisizing compound...

if you want to heat coat or wrap the headers NOW is the time.

install isnt hard, so good luck! post up if you need anything. And yes, you are going to need to fab up a new mid-pipe

[Zackjoe15]

Awesome thanks. Already got the mid pipe fabed up and ready to go. Not looking foward to getting the old studs out. I feel like its gonna be a pain in the butt.

Would be great if someone could write a DIY for these heads. Maybe I'd get one xD.

[Zackjoe15]

Ill take pics and attempt to write one during my project!

That would be amazing dude, good luck!

Mind post a few pics of just the headers when you get the chance? I am quite curious as to how they actually look as I am planning on ordering a set as well...

[thygreyt]

i have installed and removed the header several times... 4 times to be correct.

if you need any help doing so, let me know.

i never did a DIY cause it never was a "hot" item. but i can walk you through, and help you on every step.

just pm me, or we can keep it on the thread for future use.

I'm I interested in getting the obx header but what exactly and how does the mid pipe need to be customized? Can an average person do it and what's needed to do it?

Sorry for all the questions and thank you in advance

My guess would be that you need a 45 degree bend, a length of pipe, a cat if you want one, a flange and 2 or 3 o2bungs. You would need to be fairly proficient with a welder and if you don't have an aftermarket 2.5in exhaust you'll need to either expand the end of the stock exhaust or shrink the end of the pipe you have.

Where might I get the extended studs from?

I am ready to order and get the project going soon.

You will need 16 I believe.

Also, buy new copper nuts too

[thygreyt]

I got my stuff locally for less than 1$ for each stud... I got the copper things from the dealer.

Is the measurement 8 x 1.0 or 1.25?

[twizted91gt]

Uhhh you guys know the obx header comes with a catless downpipe thats "supposed" to mate up with the oem catback right?

This one does not...

[vr6-kamil]

Well this one does and it's same price. Weird I see small difference between the 2.

Has anyone even gained power from the obx header? I remember reading that only evo header made power

Thats the old style. and from what I hear, its no good. The one posted above is a eurojet copy.

[vr6-kamil]

Well eurojet one doesn't make power neither, right?

It does with software adjustments.

Even with software there is maybe 2HP gain.its really little. The only proven real life gains from any header from my knowledge was the evolution tuning header.

Now that I'm on the stock header again. I think I lost power from the Eurojet header. The car feels great with the stock header actually! Other than looks and sound header is pointless.

[SimpleStaple]

For headers, you don't need extended studs or anything... You can just utilize bolts. Most exhaust shops will have them.
