From: LB NY, Currently Socorro, NM. HELP ME!!!
i installed test pipes, and i get that rattle. i had new flex sections put in (aftermarket ones)
they also cut off alot of the y-pipe heat shielding, yet the noise still remains.
i (pretty obviuosly) have the CEL. what is the SS thing that was mentioned earlier? does that help?
ps- i tried non-foulers, but they werent long enough for the o2 sensor to fit in. anyone know where longer ones can be found?

This is a picture of the GTM TPs on my car which will give you an idea of how long the "extenders" have to be:

i just recently stuff my sensors with ss wool. its been about a week now. crossing my fingers to keep the light off. if not, then im gonna also try the 2non foulers.

Cool, but IIRC I don't think anyone's had problems unless the 02 sensor broke during install. Let us know how it goes

only way you're car would run WORSE is if you have a major exhaust leak since secondary o2 is for emissions only... or i've heard if you got MAJOR rattling issue it causes phantom knocks.

im a big car guy but newbie to nissan world. so wats up with this wool stuffing? stuffing in front of the secondary o2 to reduce signal it gets? i wonder how long it would stay though
