hey guys,jus got 08 nismo has takeda intake n full grip exhaust, i was gettin a squeal from back pressure, dealer said it was the baffle in one of the pipes....also the check engine light also keeps coming on readin o2 code i changed the bad sensor now these idiots are sayn its the catalyic converter, n their trying to tell me they wwanna put the stock ones back in cuz their better, idk muchbbout it but i dont believe that,any advice or help appreciated,btw it sounds beast

 

hey idiot what dealer are you going to i noticed you were on long island what do you have in place of the stock cats

 

sounds beast brahh best quote ever.

 

Confused more info/pics

With what's given I'll say that you have and exhaust leak. I say contact ARK on gaskets and replace your gasket and have a shop/DIY check your exhaust. But if your running HFC from the sound of it. That's normal to have rasp/whistle.

 

Did you spell your username like that intentionally?

 

You have too much turbos.

 

What do you have instead of factory cats? What code is it throwing?

I tried to google you, is this a pic of car?

 

Heh, just pullin your chain. If you're runnin TP's, you can expect to get the code for the lower O2 sensors. Even with ART's or with the nonfouler fix, it can still happen.

Have you tried clearing your codes? If so, does it come back? Someone above mentioned ART pipes, but I'm not sure what you're using.

Can I Haz moar info, pweeze?

 

lol,going tgere today ill take pics,i believe its aftermarket cats.....idk muchbbout this someone had done this exhaust b4 me...

 

I thought I answered this in the aftermarket NISMO exhaust thread? This is STILL the wrong forum. Post in the tech section in the VQ35HR sub forum.

 

I know for a fact that aftermarket cat will throw a CEL. But if you dont want your CEL on you need to get the factory cats back on.
