Packets between OSPF 2 way neighbors
CheesyBread
Do 2 OSPF routers showing a 2 way relationship exchange any kind of information on a regular basis?

I'm pretty sure it's just Hellos in a stable 2-way state.

<-- Not 100% definitive but you could run some debugs to see exactly what happens.
Seeing as there are only these packet types (below) which are associated with states after the 2-way state, if a router never passes the 2-way state (because there is already a DR/BDR) then it should never exchange them:
Hello - Used to establish communication with directly connected neighbors
Database Descriptor (DBD) - Lists router IDs from which the router has an LSA and its current sequence number
Link State Request (LSR) - Request for an LSA
Link State Update (LSU) - Reply to an LSR with the requested information
Link State Acknowledgment (LSAck) - Used to confirm receipt of link-state information
