Exhaust part numbers

[Island_Yota]

Trying to get rid my exhaust leak, Im repairing the "Front exhaust pipe" its the pipe between the manifold and catalytic converter with the heat shields and stuff.

I need part numbers for the two smaller round gaskets at the connection between the "Front exhaust pipe" and the manifold and I also need the part numbers for the gaskets at both ends of the catalytic converter.

Im going by this diagram:

Should I replace my O2 sensor aswell?

Click on the number pointing at the part you need and it wil give you the Toyota part number and list price

Just a hint...Dont get the Cat converter gaskets from any local parts stores, everywhere i have tried, its always the wrong gasket. Its listed as the right one but its always been too small.

Anyone recommend a good muffler to put in place of my pacesetter one? The 2.5" pipe is in good shape but the muffler sounds like something let go in it(rattles). Something quiet would be good like HKS or Tanabe.
