Hello and welcome
The exhausts are known to be louder on cold start and settle once warmed up, may be something to do with the tuning of the engine and the fact V-Tec will not engage until a curtain temperature. Other than that, if the exhaust is fitted correctly if may be one of the heat-sheilds has worked loose as they do and rattling on the exhaust.
As for the slosh/whirling sound, these cars are also know to leak. so there may be water in the doors, see if the bungs at the bottom of the doors are still in and if so remove them and see if water trains out. the next place to check would be where the pollen filter is, if the air-con train is blocked there may be water building in there too.
