Glad things worked.

Mine finally got here after the first set went MIA during shipping.
I'm having them Jet-hot coated but since the car is soon to be put away, I'll wait for spring to install.

I too have been waiting to put mine on until I can resolve this issue. I was toying with the idea of making my own section 1 with the same cat the m3 guys use, but if adding bungs works, might just go the easy route.

This is good news! I've been following this thread for a while hoping to learn what the problem might be since I have headers going on the car in a couple weeks.

So it looks like nobody who has modified their stock section 1 is throwing codes now?

I really hope you don't update us with a CEL in 100 miles. Great news with the simple fix! Another good reason to do the work yourself! I am not surprised you got a leak if they reused the gaskets between the header and section 1. Those gaskets should only be used once.

You and me both. I'm confident it's fine now as I've got plenty of miles on since, and everything is perfect. Usually it would light back up after a few cycles. I think if a CEL came on now... you'd be reading about me in the news (bridge. jump. and so forth)

Interested to see how this pans out. Please keep us updated.

so I am trying to follow all of this but does ESS make a tune for euro headers with out having to relocate the 02s?

Blind32 · 11-17-2011, 03:52 PM

ESS makes a tune that will make it so the light doesn't appear. If your inspector plugs in and reads your ECU, like he is supposed to do, your system will read "not ready" which will be a failed inspection.

They turn off the signal from the oxygen sensors. That's how I understand it.

^that may be possible,

In my conversation with them, they basically do a Euro tune that still requires O2s in the Euro position.
The O2s are still on & hopefully will pass inspection.
This is what I'm doing.

avsbmw · 11-17-2011, 04:27 PM

hmm I live in VA where they do not do plug ins

txz4 · 12-18-2011, 10:14 PM

id love to see how this works with the DKF section one thats catted.

InTgr8r is bang on. ESS will not even give you a tune to begin with, if you have a CEL due to your rear 02's not being connected or relocated. Their tune only turns down the signal, but there needs to be one nonetheless. They do not turn off anything.
This project is relatively easy to do, and after having solved my issue (exhaust leak) I'm happy to say everything is perfect and CEL-free.
Should be interesting to see when the DKF system comes online.

avsbmw · 01-13-2012, 09:16 AM

quick question. I have my O2's relocated. Where do you get the EGT Bung from? Or do you use your old one?

Can someone explain this comment please? Why is there a significant heat rise caused by changing headers from an to euro?

Thanks

Jumbosock · 03-07-2012, 08:14 PM

NeoGeo-
I also puzzled at this statement when I read it a long time ago. I know that some aftermarket headers come closer to certains parts of the car... like the FCAB. However, for an OEM header the fit should be great and all existing heat shields should be sufficient. Cats can get super hot because of the bottle neck they create... so I would think the area in general would be less hot with euro headers. Adding boost is another story.

Hey Ian,

Where were you going to have these coated? Going to drop them off before winter is out...

glad I'm not the only one that's confused by this...

Glad I read through this thread before I begin my attempt at the CSL headers.

With OE euro there isn't.
3rd party / ebay headers are a different story.
Many of them have to have flat spots hammered into them to clear engine mounts etc.

If anything OE euro will lower the temps because they get rid of the CATs.

Adding a coating will lower heat loss & get the section 1 CATs up to temp faster & improve flow.
The place I have used previously is

They have a Toronto drop off location.

All my issues were caused by ONE faulty gasket. Period.

This is a simple mod that nets results without issues. You're not going to melt mounts and other such bs if your sticking with Euro headers.

Our cars came from the FACTORY in Europe this way, and all ur doing is mimicking it. Easy.

NeoGeo · 03-08-2012, 04:24 AM

Thank you! I figured as much. I managed to find out about fireball via some quick googling last night.
