Hey guys, I'm throwing the common P0420 code on my 06 evo IX, I'd like to disable it. However, they are saying that if I disable it, I will also disable my rear 02 heater and throw more codes. Is this right? I've been throwing this code for 5 months now and I'm tired of looking at the SES light. How do I go about disabling this code? I have an HKS catless TBE if that helps any. I'd appreciate it guys. Thanks in advance.

Yep, been searched. I've searched myself and came up with nothing.
