Got it back this am - codes cleared out. Runs great and no new CEL - 60 plus KM put on since installation. A few start cycles etc. In and outta Zmode with the valves cycling - all great since adding the spacers/mini cats. The tech double checked everything for system leaks as well. Gaskets etc.
I also stopped by my GM dealer - spoke with the shop manager that deals with warranty - they have zero concerns with the Cats being installed.
Obviously they won’t warranty from the Cats - back but everything forward of that - no issues he said. He even had a look at them and got in there with his flashlight. Said “good to go” fwiw.
