Metal shavings in your exhaust is not good. Enter those codes in a Google search and you will find out a little more about what the car is trying to tell you. I would not be driving that car until you know what is going on.

I would also recommend that you pull the oil into a clean drain pan and inspect it for any metal fines.
You should be able to filter it through cheese cloth or even a couple of coffee filters.
You should also pull the filter and look for metal shavings.
If there is any doubt, I would replace oil and filter and run for short period and drain, inspect, and replace again.
This should at least rule out metal originating from internal engine components.
I just pulled apart my 06 because of a hydrolock event, bought it that way.
One cylinder had bent connecting rod and chucks missing from skirt.
If at any point noise gets worse, stop running engine.
Did something unusual happen or did you crank on it and then noise started?

Dunno how OP evaluated his exhaust.
I blew chunks out my exhaust once on my 68 Mustang. When I pulled the head you could reach down into the sump as there was no piston, rod, cylinder wall, etc.

Maybe it is exhaust/injector sensor driven causing knock but it may be coincidental with a more serious engine problem.
I know if I started hearing a significant knock from my engine I would want to try and rule out internal problems before it gets any worse.
Engine may be fine and problem related to something else. I just wouldn't want to find out the hard way while trouble shooting.

Re help
car started missing with codes for random misfire so I pulled the spark plugs and replaced them then it started the rattling on deceleration I haven’t ran it sense I’m thinking it’s a valve. I’m gonna drain the oil tonight if it looks good I’m gonna pull the heads I pulled right valve cover and everything looked good so gonna pull left side

I'd start at the cats and work your way back to the engine.

If oil looks fine, as suggested you can definitely hear internal engine issues to better isolate with a mechanics stethoscope.
You can get one for 8 bucks at harbor freight.
Just used one to find which cylinder was bad in my c6 from a hydrolock event.
One cylinder was clearly louder than the rest.
This was not detectable by ear only.
