Hello, i have a Malibu 15 LTG engine, with Magnaflow High Flow 200 Cell Downpipe, the downpipe is installed about a year ago, with disabling a P0420 DTC, because its was throwing it randomly. and about a month ago it start to pop a P2097 DTC, as i understand it related to CAT also, but why it didnt pops before ? maybe a cat is degraded ? ( Drove about 15000 Miles ).
May i safely disable this error and forgot it, or try to figure it?
