Need a bit of advice ... have check engine code P0420 - Catalyst Efficiency (bank 1). 2008 JKUR and currently at 82,000 miles so just out of warranty.
I've had this code for about 8 months and don't notice any performance issues. Should I just ignore it?
If in fact I need to replace the cat system are there alternatives to just replacing with OE part that could be of equal or better quality and maybe improve performance at a similar price point?
What are some proper diagnostic procedures that I should be aware of if I take this to a local exhaust shop? Like could it be just a sensor bad and if so should a good shop know how to test for that vs. just selling me a new system?
Fairly new to the forum here and am enjoying it greatly. Appreciate any advice and insight.
