A twin Cessna pilot reported an engine failure and diversion to a nearby airport.

Narrative

I departed ZZZ1 and XA:40 time with a destination of ZZZ2. I was flying a Cessna 4XX Ram VI single pilot. This flight took place at night on an IFR flight plan; although I was in VMC throughout the entirety of the flight. On climbout; I was receiving radar vectors from ATC and climbing to 11;000 feet; as assigned. At approximately 5;000 feet; the oil pressure and manifold pressure on the right engine started to drop steadily. This took place after CHT #6 (on the right engine) spiked to approximately 680 degrees F. Red line is 460 degrees F. All other CHTs on both engines stayed at normal operating temperatures. Over the course of approximately 2 minutes; the right engine lost complete oil pressure and power and feathered on its own. After noticing the initial loss of oil pressure and manifold pressure; I initiated a climb and pitched for blue line speed. I completed my immediate action memory items during this time. As the power continued to decrease; I started to look for nearby airports to divert to. I then requested priority handling with ZZZ Center and squawked XXXX; advising ATC of the priority reason and intent to divert.I found that ZZZ was approximately 20 nautical miles away from my present position and noted that the longest runway was adequate for the aircraft I was flying. I turned to ZZZ and began a steady descent to set up for a visual approach for runway XX. During the descent; ATC instructed me to change to the advisory frequency for ZZZ. I entered a 3-mile right base for runway XX and made a landing onto runway XX. I exited the runway onto a taxiway after touching down to avoid getting stuck on the runway. After exiting the runway; I got stuck on the taxiway and was not able to taxi to the FBO due to the asymmetrical thrust from the left engine and the left nose wheel steering input I was making. After shutting down on the taxiway; I called ZZZ Center to let them know that I was on the ground safely and also made them aware that I was stuck on the taxiway. I attempted to contact the airport manager after shutting down to let him know what had occurred but was unable to get a hold of him. I called ZZZ Center back again and they sent Sheriff's Deputies to my location. The deputies got a hold of the airport manager and once he arrived; he towed the airplane to the FBO. Prior to this flight; the airplane had flown and performed as expected within its published operating limitations. After the incident; the engine was shipped to a maintenance facility where it is currently being serviced as of Day 0. The return to service date is unknown at this time.
