Yes I was running the OEM cat on the nitrous, only ran 2 bottles. Nitrous has no effect on catalytic converters. Usually it's excessive unburned fuel, coolant, or oil that ruin cats. Either that or the catalyst gets knocked loose. I haven't taken mine down yet to see the problem, but I have bottomed out quite a few times.
