Delete some characters from header before bulk load

You could specify the complete or relative path of the other pipeline in the Pipeline property of the Pipeline Execute snap. For example, if I was in “KoryK/examples/test1” pipeline and wanted to execute “KoryK/support/example4” pipeline, I would simply put “…/support/example4” in the Pipeline property.

Note that the calling pipeline would not complete until the child pipeline completes, even if it doesn’t use the child execution response.

It is preferred to execute a child pipeline using the Pipeline Execute snap, but there are use cases where calling via REST Get will work, especially “fire-and-forget” scenarios, as you are describing. Passing pipeline parameters via the REST Get can be done through the Query Parameters setting in the snap.
