Ok, well I was planning on picking up the car tomorrow cuz that's the last time I'll be able to get a ride to pick it up for three weeks and order up a new OE pressure regulator and either OE or FelPro intake manifold gaskets, not sure which yet or if I should replace the common chamber and throttle body gaskets too, what do you guys think? And replace the gaskets, pressure regulator and regulator vacuum hose well my dad is out of town then bring it back to the dealer for a new cat or two. when he gets back, But since you say "It's quite possible the first jammed cat burst the intake gasket with hot backpressure" I'm worried I'll burst my new intake gasket on the way back to the dealer, But I'd hope the metal reinforced FlePro gasket would let that happen.
