Has anyone deleted all the cats and ran an o2 defouler on a stock ECU untuned? Is it possible to do this without throwing a code? If not why? I swear I read there have been some people who've done this with success.
I purchased some 90 degree o2 defoulers that are catted and inlet size is reduced.
I swear I read someone successfully doing this in the past. I've also read someone saying it's not possible.

It's been done, you can find it if you search here. But then other guys say it didn't work for them... If your warranty is already expired just use HP Tuners...

Good to know. I swear I saw someone be successful here but I couldnt find it again. It might come down to different o2 defoulers I'm thinking
