Engine light code - P0430

Hey, new to the forums just looking for some help on my '04 ram 1500. My engine light has been on for awhile and I cannot pass inspection. The code I am getting is p0430: Catalyst System Efficiency Below Threshold (Bank 2).

I searched around online and it sounds like an O2 sensor problem or an exaust leak. Problem is, is that im a broke college guy with no tools or a clue to under the hood of cars. Are there any cheap fixes just to get me to pass?

Thanks

I used to get that code when I put high flow cats on. Installed some non-foulers and the code never came back. I pass PA inspection with the non-foulers on.

Go to Autozone and but the Bosch O2 (P/N 15504) for $25 and replace the pass side front O2 and reset the PCM.
