I had the toyomoto headers on for about a year but it was so raspy I had to take it off. I wish I still had some sound clips. GL with the installl

I wouldnt go with an o2 sim, even though it works. It hides a few codes, other than the o2 sensors. Like your knock sensor, for one

I will be going this route with my HP racing headers.

You will need to do it to both post cat sensors. The ones past the cats. No need to do it for the pre cat sensors.

Good Luck

Its because there was a leak

The o2 simulator will not throw a code for the knock sensor, along with the rear o2 sensor.

yea i think taco is right..i dont see how the O2 sensors have anything to do with the knock sensors..unless you are pushin boost i dont think you will EVER (or should ever) have a problem with the knock sensor..
