I'm not sure what it is exactly. Is it a replacement for a catalytic converter? Or does it go behind the cat?

There are 3 major parts to the RX-8's exhaust system:
1) The header
2) The catalytic converter
3) The muffler

They connect together from the engine out to the tailpipes.



A "midpipe" is the "middle pipe" and replaces the catalytic converter in the line.
