Tc1-p0420 Cel
I got a CEL today with TC1-P04020
The error code was Catalyst System Efficiency below threshold (Bank 1)...
I assume one of my 100cel cats (fabspeed Supersport) has finally gone bad???
Any other ideas?

that's pretty much all I do...highway driving...
The CEL came on when driving locally (slow driving).... we'll see... worst case...i'll go to a straight pipe only system...

That is when I decided to install my Fabspeed Sport back on to avoid any CEL's until I get the chip tuning for the straght pipes. It is possible that one of your 100 cell cats have gone bad.
