This weekend I was driving through central TX when all of a sudden (not really all that suddenly, it had previously sounded like I had an exhaust leak) everything got really loud. I pulled over and found that a weld on my header, a few inches before the Cat coupler, had completely broken. I jerry-rigged it with some wire so it would not drag and got myself to an autoparts store fast.

It's a 1991 240 non turbo with the O2 sensor mounted on the Cat. I'm not sure where an EGR mounts in, but it does not look like there is anything between the Cat and the E-manifold. Is there a way to decide which one I need? IPD and Autohaus show 3 of them and they need chasis numbers. But most of the Car-Parts.com folks I have spoken with don't have chasis numbers on the part.

The Pipe on there now has a spot to mount the O2 sensor to the pipe, though it is on the Cat. So I guess as long as I get a head pipe with the right couplers I can plug the O2 hole and rock and roll.
