I was just wonderin' if the duramax's are like the cummins an have a silencer in the intake an if so can they be removed? Does it have anythin to do with te top plastic cover an why does the intake tube split into it??

fill out your signature so we know what your working with.

but that chamber on the top of the engine is somewhat of a silencer. i blocked mine off with a paint cap.
