It's integral to the exhaust manifold. To replace it, you replace the entire manifold.

Here's a guide for installing aftermarket headers: http://www.ppeengineering.com/docume...350Install.pdf

You can't exactly replace the cat itself, you'll just have to replace the manifold. Removing the bolts will probably be the most annoying part, I'm sure they're badly rusted. You'll most likely need to get a torch and heat them up.
