Anyone ever get P0420? I’ve got hi flow cats in my build and hadn’t ever seen this code ironically until right after I had my car inspected 6 weeks ago. I cleared the code, didn’t come back.
Yesterday went racing and the car ran great. On the way home, the code came back again.
Is this expected with hi flows in the heat? It was hot out and obviously racing puts a whooping on the cats. Maybe something that can be tuned out if they’re falling beyond the expected threshold? Car is otherwise running like a scalded cat and putting down 9’s easy.

Finally cut my coupler I got for my 108mm throttle body to JLT intake and put on black clamps. Got rid of the double clamp and cut up jlt coupler I’ve been rolling around on. Got some 6an hose separators coming in tomorrow that’ll fit the 8an ptfe fuel lines for my flex fuel sensor better. Here’s better pics of the setup I made and how I routed the fuel lines/connections. Hoses will look neater tomorrow after new hose separators come in.

Two 90 degree hose ends - 1 has a fore female 1/2” efi fitting connected to the end of the 90 degree hose end (connected to fuel rail) and the other has a 1/2” fore male efi fitting connected to the 90 degree hose end (plugging into the plastic fuel line jumper that used to go to the fuel rail). Fuel feeds to the sensor first, and then loops around via the 180 degree hose end and goes into the fuel rails. It uses a Motion Raceworks flex fuel sensor fuel bypass so that there’s no restriction in the fuel system. Fuel flows through the sensor, and around it at the same time. Hoses are 8an PTFE, with steel bearing around the PTFE liner, and nylon braiding over that. I custom made the wire harness myself, which tucks neatly into the front fuse box while it’s closed. No gauge if wires in the cabin - it uses a Bluetooth transmitter that plugs into the sensor, and is readable via an app live along with the fuel temp. I made the bracket out of 1/8th” aluminum. I need to touch up the paint on it a bit. Some low profile hex screws and nuts from McMaster, longer ARP bolts to secure it to the supercharger and the lid, ARP washers fit perfectly in the circles in the supercharger lid, so the bracket makes no actual contact with it
