I looked under, around the catalytic and could feel a strong airflow in my face coming from manifold/down pipe area but couldn't locate a crack or where it was coming from, it even tore up that fabric material (heat shield insulation?) around the down pipe area. It's raining hard so couldn't get a great look but it's def coming from behind the lower engine area, crossing my fingers for anything but a busted engine.
