Hayes' Encounter Report for 28 May 1944. Here’s the relevant section:
Taking up pursuit again I was able to get on one of the Me-109’s which now began to dive. I fired three short bursts. After the first burst he skidded, I suppose to look back. I fired again seeing debris and canopy come off. Just as the third burst was fired it looked like the pilot started out, however at that instant strikes were noticed on and around what looked like the pilot. Then the ship actually disintegrated. I went out of control indicating 500 mph. at 20,000 ft. and so did my wing man. I picked up my element leader, Lt. Howell, quickly and covered him as he nailed a Me-109 with the pilot parachuting. We climbed back to the bombers from 12,000 ft. and continued the escort. How the enemy pilot came out of his plane at 700 mph is beyond me.
Please take careful note that Hayes records his speed as indicating 500 mph. He then concludes his account of this combat by noting that the enemy pilot came out of his plane at 700 mph. Now it just so happens that 500 mph indicated at 20,000 feet is approximately 700 mph TAS. 700 mph TAS at 20,000 is approximately Mach .989. It’s not plausible that the dives actually reached those speeds. One possible explanation is that Hayes failed to account for instrument and compressibility errors when he did his quick calculation to arrive at 700 mph TAS from 500 IAS. Certainly Hayes and his wing man exceeded the P-51's recommended dive limits, and fortunately for them, their aircraft apparently were no worse from it as they went on to complete their escort mission. The Me 109 wasn’t as lucky since it "actually disintegrated" during the dive. We’ll never know if it was the bullets or structural failure.
Please see Encounter Reports of P-51 Mustang Pilots, in particular the section titled Dive, for more comments from Mustang Pilots relating to the speeds recorded during a dive while engaged in combat.
Please see also Army Air Forces, Air Technical Command report on Dive Tests on P-51D. The report records the highest speed obtained during a test dive was a maximum true Mach Number of 0.85; concluded that the standard P-51D airplane may be safely flown to a Mach Number of 0.80; and in extreme war emergency the airplane can be dived to a Mach Number of 0.83.
