Header install question.

[kevin FaKiN spLits]

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

But longer studs is the way to go. My old Eurojet header came with longer studs and 20 copper nuts...

Getting the exact length right with bolts is tricky.plus you really can't ensure they won't rattle loose.the copper nut is used to ensure that doesn't happen.another option is to use blue loctite and thread it on then pull the nut, let it air dry then put the stud in and nut over it.you don't want it permanent so letting it dry gives it a snug connection without locking in place

You use locking washers. It works.

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.

The gains are power across the entire bands. 3rd feels better, though car still needs to adjust.

So I get a ride on thursday right? then I can see if the install is worth it

I just picked up this OBX headers and other then getting longer bolts, is there anything I'm going to have to modify to install them?

I have mine installed. Need a custom mid pipe. Your's came with the gasket, right?

It came with a gasket for both ends. That's going to kinda suck for me. Don't have anything to make custom pipe

[Jinto24]

I got another question about the install. Just wondering if any of the censers have to be moved

[JohnnyDrama]

It does with software adjustments.

It does? Can you show me?

the only sensor that moves is the one that is on the oem headers, it'll go on the mid pipe so it does get stretched out a little bit to reach further down the exhaust tunnel. the other 1 (or 2 if you're like me and have the PZEV car) stays in the oem location.

[Jinto24]

So I now have the OBX headers installed and I now have a whistling noise. Did you have the same problem or know how to fix it?

Sounds like an exhaust leak. Did you use longer exhaust studs when doing the install?

[Jinto24]

That I did
