I'm trying to put invidia 60mm test pipes on my 2003 Nissan 350z I also have a invidia cat back but putting the test pipes what do I have to do to get my CEL to not come on I've heard non foulers but that they also screw up your ecu help please

 

You shouldn't be getting the CEL if you have the 03. You're fine. I had Helix test pipes on a long time ago, now I have resonated TopSpeed pipes. No problems. Just to be safe, I would disconnect your battery before doing the exhaust modification.

It won't mess up your ECU.

 

Awesome thanks man

 

Smooth, are you just a mind reader and knew he was thinking about this question? o.O

 

I made a thread already, but since there is one open here,

I have the same set up but mine is an 05 track.
I got p0420/p0430

I will need defoulers?

 

Yes, or have your tuner disable the sensor. If your emissions requirements don't need sniffers, you will pass testing. Computer will just read the sensor is Not Ready, but doesn't count as a code.

 

I have berk technology test pipes. And I am throwing the Lean code p1273. Probable causes being A/F sensor problem, vaccuum leak, or I might need a tune to correct the problem. I am thinking of getting a tune after I throw on my plenum spacers in a month or so. Also when I let off gas at 65+ mph I can here a hiss coming from the test pipes. Does this sound like a leak? The code didn't come on until a week after my test pipe installs and after I went full WOT to show off to a girl -_-

I wonder if disconnecting the battery for 30 mins would correct this problem, provided its not a bad sensor or leak?

 

When I installed my test pipes I just left the battery unhooked while I was installing them. I never got no code for running lean

 

False on the 03's not throwing a CEL. Mine threw it almost immediately after I installed my test pipes. Might have to get the non foulers

 

Not to thread jack but what about '06 models? Anyone know if the Bung Extensions from Z1 (Just non foulers) would work for all gens?
