Default P0430 CODE -- system Catalyst issue?

My car threw code p0430. Is that becasue I run Long Tube headers? I have had my headers for 2 years and never threw this code.

Also my super chips wont erase it. Any ideas on how to fix?

Yes that code is from a rearO2 sensor. Here is an old thread on antifoulers that may help that issue http://www.dodgeforum.com/m_539943/tm.htm

Diablo has an option to "delete" the rear O2 sensors, this just makes the PCM ignore them, personally it has worked great for me.

Just a thought... since it took around two years for the code to pop up just clear the code (pull fuse 11 for a few seconds) and see if it comes back any time soon, hopefully it's will not pop up for another two

I forgot to ask, do I need to de-program the Super Chips before I pull the fuse 11 or can I leave it isntalled?
