Headers and Y pipe = Check engine light?
I recently put on a set of pacesetter long tubes and an replaced the cat with a Y pipe on my 2003 1500 5.7 and the engine light will not go off, i know its just something with emissions but is there a way to bypass that O2 sensor so it doesn't throw codes to the computer?

https://dodgeforum.com/forum/3rd-gen...ving-cats.html if you only had one cat, you'll only need 1 fouler. put the normal o2 sensor in one header, and the other o2 sensor with the fouler in the other header. if you had 2 cats, follow the DIY

Any clue where i can pick up the correct non fouler for it? I went to murrays today and they only had a 14mm one which wasnt big enough becuase i had them get the O2 sensor out and when i tried screwing it in, the actually sensor end wouldnt even go in. Anyone know the correct size to get for an 03 ram after cat o2 sensor?
