Narrative:
Enroute; after initial climb to 13;000 feet and setting cruise power; I began to feel disoriented; confused; nauseated and groggy. I was wearing O2 and checked my O2 saturation and found it to be 97%; however my pulse was 130. I was concerned but not alarmed. However; I found that my fingertips and end of my nose began to tingle and feel numb and I became alarmed. Since my O2 saturation was good; I suspected co effects from an exhaust leak and was concerned with my ability to continue the flight. Since I was feeling ill; I decided that the best decision was to land immediately. I was near and airport notified ATC that I was declaring an emergency and began an emergency descent to [a nearby airport]. I landed uneventfully 5 minutes later. Since I suspected co (carbon monoxide) poisoning; I left the plane [there] and hired an a&P to inspect the plane for exhaust leaks before returning to retrieve the plane. I continued my trip via commercial airline.although I do not have proof; I strongly suspect an exhaust leak and co poisoning as the plane had backfired in the day previous; which was unusual. Knowing that a backfire could indicate an exhaust leak; I should have removed the cowling and closely inspected the plane before flying again. The long climb; flown rich of peak mixture probably contributed to co entering the cabin. Additionally; I have purchased a co detector for use in the plane.

Title: SR22 pilot reported feeling the effects of suspected carbon monoxide poisoning; an emergency was declared; and a divert accomplished.
Narrative: Enroute; after initial climb to 13;000 feet and setting cruise power; I began to feel disoriented; confused; nauseated and groggy.

However; I found that my fingertips and end of my nose began to tingle and feel numb and I became alarmed. Since my O2 saturation was good; I suspected CO effects from an exhaust leak and was concerned with my ability to continue the flight. Since I was feeling ill; I decided that the best decision was to land immediately.
