I just installed Megan testpipes and... CHECK ENGINE LIGHT!! HELP
ok, i just installed megan testpipes and megan ypipe. when i installed it yesterday and took a test drive, the check engine light did not come on.
Today, i turned my car on to warm it up for about 10min the check engine light came on. My state inspection expires this month and i need to get inspected.
I saw some of the videos that would fix the check engine sign due to installing testpipes and they would use non-foulers? and drill them to connect on the o2sensor which makes the ecu to read it as a oem cat or something..
you know g35 coupe has 2 o2 sensors on the oem cat converter and another 2 on the headers.. am i supposed to use 1 non-fouler on 1 o2sensor? or am i supposed to use all 4 non-fouler on all 4 o2sensors that are on my testpipes and headers? i'm not rich enough to drop my car to the shop to fix them. most of basic stuff i can do it myself in my garage.
please give me some advice what i could do to fix the check engine light before i get my car inspected without FAILING
PLEASE HELP GUYS!!

i thought of getting inspection before doing the testpipes. when i was installing ypipe first someone told me to take out the negative cable when working on the cat converter so that o2 sensor gets reset. i just did the non fouler on my o2 sensor and when i turned ignition it still threw CEL. i don't think this is going to disappear if i drive about 50-100miles.. sucks thing is i already sold my stock cat converter so i can't even put them back on for testpipes.. do you guys think the reseting ECU will help getting through the state inspection?

Yeah I'm not quite sure why you didn't just wait until you did the inspection and then installed the test pipes.
Next time if you could just take some time and do a quick search, you can find this topic has been discussed many times.
I found this info, literally, within a minute of my search.
Basically you can follow this DIY: http://www.my350z.com/forum/engine-d...-fix-pics.html
Or you can buy these from Statik, a vendor on this forum.

As far as I know if you reset your ECU you will still fail. For emissions here if the ECU was reset, it'd cause a "readiness" failure regardless if there's a check engine light or not.

I'm gonna have to agree with mkvl. I think here are your options
1. Take the time to buy the 90* angle non fouler or to do the DIY in the link I posted. Slim chance the light will be there but if it still doesn't work that's that.
2. Spend several hundred dollars on an uprev tune.
3. (What I would personally do) Try to find some OEM cats and throw them back on there and KEEP them so that you can pass inspection every year.
4. Pay someone off to pass you.
