Narrative:

Departed after normal run-up. On climb out, left manifold pressure dropped to 26 inches. Adjusting throttle did nothing. A visual out the window confirmed suspicion of exhaust failure. Secured left engine, returned to departure airport. Single engine landing completed, secured aircraft. Observed heat damage to engine cowling. The next day the mechanic looked and found that the wye connector on the right bank of cylinders had failed. This caused heat damage to hoses downstream.
