so a couple weeks ago after taking my truck out to play in the mud i noticed what sounds an awful lot like an exhaust leak. after washing the truck up i looked around and couldn't see anything that looked obvious but it's definitely coming from the driver's side. i noticed after searching around here that the 4.6 is notorious for this kind of behavior for one reason or another. do the manifolds usually crack in the same spot or is it pretty random? just wondering where i should start to track this down. it's really annoying and doesn't go away when the truck warms up...
