I notice a guy had a stock gt exhaust on sale on ebay but I saw 4 02 sensors on the exhaust. My question is will upgrading the exhaust and removin those trip a check enging light or worse so performence? (smog check)

I have a civic now and it only has 1 02 sensor so 4 on the exhaust is news to me.

let me knopw thanks

What year was the stang?

 

Yes removing any sensors will trip the check engine light on OBDII systems.

Are you thinking of putting Mustang exhaust on a Honda?

 

No what I am saying is a guy on ebay was parting out his whole 2005 Mustang GT part by part and one of the parts he had for sale was the STOCK cat back and he said it included the 4 - 02 sensors! There was also a picture of them and it showed them all toward the back. It was really wierd but I am wondering then if your installing a after market exhaust does it have the holes for the 02 sensors and if not is it setting off a check engine light?

thanks

There are no 02 censors on the 2005 Mustangs from the cats backward (as far as I know). Just disconnect your battery so the computer will tune itself to the new exhaust. I've put 1000mi on mine since putting on a Magnaflow catback system. No check engine lights or any other problems. Earl
