I used to have test pipes with my Injen TD and then went to HFC to eliminate the rasp.

I recently went to a single HKS and may want to go back to test pipes.

My question is that when i had the test pipes, i couldnt get rid of the O2 code it was throwing on the banks.

anyone know how to fix this? i know there are O2 bypass sensors but my experience with them is that they dont work.

any info will help

THANKS!!!

Disclaimer: I did a search and couldnt come up with any relevant information on how to solve this..

(just incase the fire team shows up)

 

anyone?

I would suggest the non-fouler trick. It only costs about $10, and is very easy to do.

This is what I used on my car with test pipes and I have put a few thousand miles on it since the install with no CEL.

 

orrr you can go to a Tuner like i did and have them delete the code completly so it will Never pop up again

 

How possible is this to actually do?

 

UpRev tune can essentially "tune out the code".

 

Do you have emissions testing required?
