Hi...I got a civic SI 1996. I've installed a Magnaflow exhaust line, but my catalitic converter is again upon it, because if I remove it, the 02 oxygen sensor will always say to the computer that my line is cold and will shoot to much fuel to the engine. You surely know that. So, i want to know what I can do with that without install a high flow cats.

Thanks

(Sorry i'm from quebec in canada)

 

Are you trying to say that you want to get rid of the Catylytic converter and just put a straight pipe there? If that is the case, it might be difficult because you have the extra o2 sensor after the cat, but I am sure someone on here will help you.

 

That's it man! I want to know how to bypass 02 oxygen sensor without create a trouble and light on my check engine.
