Well first and foremost I would recommend to fill out your profile. This is a great place for help and knowledge and you have nothing to fear 
Second, I will try to help you. DTC P0430 is System low efficiency bank2. What is the condition of the catylist? If the converter is partially clogged/damaged/bad/loose etc it can cause the problem. Also ck all pipe connections and make sure the exhaust has no leaks. And finally, did you remove your kitty and forget to add a sim??? Good luck bro

If you just installed new exhaust you can have that code thrown up...its a low pressure threshold on the banks......I installed corsa exhaust and had that problem. Go to Summit and by 1996 Impala LT1 O2 Simulators....It will fix the problem right up
