Im planning on getting berk test pipes. Have an 03 so hopefully cel is not an issue. But, if it does show, would it hurt if I don't get the cel fixed? Thanks.

 

There are several excellent discussions here about oxygen sensors and ECU feedback. Very enlightening.

NOTE: The discussions are enlightening only if you review them. If you start a thread and never return, as you have done here, you are wasting my time. It will not happen again. Welcome to my ignore list.

 

why dont you just buy the mini cat to put on your testpipe so you dont get a cel. pm if you dont know what it is.

 

You wouldnt know if something actually happened to set the cel on..
Can cause some issues

 

It is a post cat CEL , all it does it tell the computer that the cat is properly working. No harm at all, just a CEL. Pre Cat CEL you need to worry about. An 03 should not get a CEL, i had no problems on my car.
