I'm getting the above set-up shortly, along with a high-flow converter. I have two questions - is a new O2 sensor a good idea, and where is it located at? I don't know if we have an O2 sensor after the converter or not, I know of the one on the manifolds somewhere. Just wondering if I need to replace a sensor when I get rid of the old intermediate pipe, that's all.

 

I have a full Edelbrock setup with a Catco cat on my GTA. The single O2 sensor is on the driver side header collector. A new O2 sensor is a good idea, even if you think you don't need it.

Turns out I got the wrong converter (universal sucks) , so I'll ship it back and hope the existing converter is still good. If not, I've got to do some chopping and welding to get it to connect to the cat-back - it's missing the flare joint! If it's in good condition, I'll go ahead and stick the cat-back on and leave the conveter for after the stroker build, I plan to do headers (Edelbrock's emissions-legal ones) and y-pipe at that time.
