PPE header & CEL

Im still amazed that a member in our forum got pissed at me for saying that these header installs cause these CELs . Still haven't seen a stock ISF with a CEL with these codes. The cars are not designed for these headers, the sensors are not designed for these headers and added flow, and the routing of the lines for the headers are not designed for the heat coming off of these things.
You have to pay to play and to each his own ( if the recurrent issues dont bother the owner) , but I cant believe someone would say that these headers dont' create these CEL situations .

Lots of variables really. Improper installations, improper routing, maybe sub standard extension harnesses, etc seem to cause the bulk of the issues.
It's not really exclusive to this platform. You have a sensor that measures catalyst efficiency, and you remove the cat, you get a cel. This is something every platform deals with. We just don't have the luxury of having the ability to access the ecu to remedy it. The current workarounds are bandaids.
I'd like to know how many people who've shielded their wiring have ran into malfunctioning harnesses?

If the Installation is done correctly and the o2 sim is installed properly and the stock sensors are in proper working condition, you won't have an issue. My last car, an Infiniti G35 also had headers. They were Crawford Headers and I sold that car with the headers still installed. Those headers had over 30K miles on them, and that car never did self destruct. Both Crawford and PPE make quality stuff. I did my homework before I went with both of them.
The palaver you're spreading is simply not true. I have over 50K miles of installed header experience, what experience do you have?
To say the added flow is a problem, man you're talking out of your ears.

It isn't the headers that cause these CEL issues, the physical header is a solid design. 90% of them are due to bad routing of extensions, or incorrect wiring of the o2 conditioner. We haven't had a whole lot of complaints on the extensions, we use them on the IS250, IS350 and ISF as well as some other cars. We have sold/used about 500 of them and sent out a hand full of replacements (mostly due to melted wires).
I have contemplated moving the O2 bung to one of the runners in the header so that the o2 sensor extensions are not needed. This however is not the correct position for the sensor, though many headers come this way.
I have personally installed 10+ sets and have never had a car leave with a CEL or call me back on one that I installed. I wish I could install them all here, but it isn't possible.
If anyone has any issue with them, please contact us first for support.

i scan the code yesterday came out as P2198 bank 2 sensor 1, o2 sensor signal biased/stuck rich...I cleared the code but didn't drive enough for it to cycle through yet. Drove to work and everything is still ok, keeping my fingers cross. I think I will find out on the way home but hopefully it was nothing. I will check on the sensor after work.
my car is 2006 GS300 but I believe the same fix applies for all.
