this is a puzzler but i would first check to make sure he didnt suck anything into the cooling system that may be blocking it. Check the powersteering cooler and the oil cooler if he has one. Also it may help to dril the (I think it was 2 x 1/8" holes) in the thermostat to relieve any steam pockets he may be getting.
If all he did was just put on mufflers then maybe he may have rust deposits in the exhaust manifolds causing some blockage??? I'm just throwing out ideas here....maybe some who has had the same problem can better help ya... Good luck
