This setup includes a random technology 3" catted down pipe with metal substrate cat.  Random Technology sells Catalic converters to Companies like Cobb and Daddy's SCP.  This is the highest flowing cat you will find that is guaranteed not to throw a CEL.  The set up also comes with a Random Technology 3" Third Cat eliminator, this part is pretty much self explainatory it eliminates the 3rd cat in the 04-05 WRX/92X.

To complete the stealth back I have a daddys SCP 3" rear midpipe with flex section.  This is their best and highest selling model.  One of the best mid pipes you will find.  It mates to your stock muffler for a perfect *quiet* stealth back that wont attract too much attention and give you a nice HP boost.  All exhaust parts are mandrel bent for perfect flow.  I have included the manufactorers links for your refference.
