I done this, double non-fouler with the drilled out one for the 02 sensor. I still get the code PO420 which is just saying the 2 sensors are similar in readings, I just use the code reader & erase. The other thing you will get is a rich running smell from the tailpipe due to not having a "cat". Haven't gotten into the computer yet to see if I can recalibrate the fuel mixture to a leaner mix but I will let you know.

I run the OBX style header (shorty) with the down pipe, kept the "res" & running a Flowtech Raptor muffler. I also have the "long" style cold air intake system.

so you would have to weld another bung onto the header to do the whole not drilled drilled fouler thing right?

i'm also wondering if i should pay to get a hig flow cat put on my exhaust before i get this header...

I don't think welding another bung would really accomplish the task cause, well, here is a pic of what it looks like assembled.

you're not putting an anti-fouler on your primary o2 sensor, are you?
