jethot coats inside and out too...

I think headers, SS-X, and Remus cans would be a nice complete system. I suppose I'll try both and see what happens.
My last chance of getting rid of my CEL will be to move my bungs approx 1.5 inches and see what happens. I can't believe it would make a difference or that the O2's are so sensitive that it'd change anything

you know my setup and its IMO just right,
The X pipe added that little amount of bass to my setup,

my cars not that raspy either, It was a little "wet" sounding when I put all the system on but it seems to be a deeper sound now,

For those who dont know I have

Supersprint V2 Stepped headers, OEM Euro cat pipe, SuperSprint X pipe, Supersprint Powerloop mufflers,

Lots of Italian steel lol

did you unfold the wiering or extended it for the 02s , IMO this bung is the best one read the site and what it says about it

OR
Is there a particular bung install that works consistently.

Those J bungs that you got are what I was originally planning to go with.
Now, I'm not sure what to do.

A couple of related things I'm looking at.
1. Are the CATs loosing too much heat by opening up the surround shields too much.
2. try to pass as much heat as possible down to the CATs by coating the headers.
- I'm planning to do this XMC coating, which was primarily developed for the diesel industry but is now being used for other applications.
It is a dual coat system that coats inside & outside of headers.

I've even cut down (shortened) my J-bungs to make them more in-line with what I see above. CEL still. I truly believe that was a waste of time.
My headers are coated inside as well, and my heat shield doesn't have any cuts or openings. A cover was welded on to keep the heat in for that reason.

So I'm a bit miffed at the moment. Still going to try moving the bungs a bit and see if that works. If not... then it'll be ESS for a tune.
Having said that... Despite the CEL, the car runs like a hot damn! Great idle, loads o power. Having to stare at it is what picks my ass.

Attachment 555494

It was unfolded from the ECU back and run similar to yours, above the heat shielding and secured well. If there was a nick in one of the wires or something was awry with the lines... I assume I'd get more of an issue than just the CEL. Things wouldn't run properly.

So it goes back next week to get the bungs moved, and the Remus cans put on. Jury's still out on OE X-pipe or SS.

Things that make you go hmmmm

^ that's the sort of thing that makes me wonder if it's pure luck of the draw with these cars.

not luck..... you just have to mark the position of the o2s very carefull not to mix them up and make the holes at the right place ...

[johanness]

^^^ Yeah, well that's my next step. We'll see.

And inTgr8r... if that's the case, I'm batting some crappy #s... Because everyone else seems to be perfectly fine.

Who knows.

to bad your not in chicago , i would have helped you with the install ....

IDK... maybe so. (hoping)
I'll be finding out for myself soon.
Headers have shipped just waiting for hem to arrive.

Mine will be a little different though;
I have the non-header ESS tune now & for $100 I will reflash the Euro tune.

good luck then keep me posted on what happens .....

[johanness]

inTgr8r... if you're getting a tune anyhow, WTH are you worried about? It's going to shut down your rear O2's regardless, so you're not going to see a CEL. You could tie your O2's into a bow tie and hang it off the engine and it wouldn't make a difference.

This whole ordeal is for those who aren't running a tune (yet). You don't have to worry about a thing

[inTgr8r]

It's not that straight forward.
O2s aren't shut down, they are set to Euro levels.
They have to be on to get past Eco testing.

I know of at least one person with ESS tune & still getting CEL.

[Blind32]

Has anyone looked into o2 simulators?

To those throwing codes: are you sure you didn't connect the post cat O2 sensors to the wrong banks? The North American section 1 physical location of the bank 1 and bank 2 pipe locations is the exact opposite of the Euro version. In other words you can't reconnect the post cat O2's by remembering which one was on the left nearest to the driver side and which one was on the right nearest to the passenger side. A change in headers to the Euro version reverses their physical location. You have to think in terms of banks.

Do you guys get what I am saying? In other words, if one uses the north american catted header, then bank 1 would end up on the the drivers side of section 1, while the EURO version bank 1 would end up on the passenger's side of section 1.

Do you guys get what I am saying? In other words, if one uses the north american catted header, then bank 1 would end up close to the drivers side of section 1 (this is only an example as I forget which side it really ends up on) while the EURO version bank 1 would end up on the passenger's side of section 1.

Interesting, first time I've heard that.

Does that mean that with N.Amer headers there is a right-left cross over in the pipes.
AND that the Euros don't?

[Jumbosock]

exactly

[inTgr8r]

I'm sure this is something easily overlooked.

Thanks.

[johanness]

Good to know for wed's trial & error day. Woot!

[Jumbosock]

I was trying to go by memory but I just double checked and am now sure that:

If one uses the north american catted header, then bank 1 would end up on the the drivers side of section 1, while the EURO version bank 1 would end up on the passenger's side of section 1.

all of this info is great! i plan on doing my headers in the next few weeks so i will be watching this thread to see what people come up with! i intend to just mark everything and insert just as it was pulled out. i think that those bungs that were posted should help to clear up the cel issue, as long as they are mounted far enough back, as it keeps the o2s raised up out of the flow to a certain extent.

To clarify, i will need:
Turner header swap kit (gaskets etc)
2 of those 02 bungs

anyone know of the best places to order both of these items? and what is the solution for relocating the egt. Did y'all just remove the one from your current headers or is there another solution.
