If the stacks are a larger diameter than the rest of the pipe, it may deepen or amplify the sound a bit. I think the main difference simply comes from the fact the sound is being blasted into the air for all to hear instead of just off to one side. The sound may be the same, it's just easier to hear with stacks.

Yep I think that's pretty much it.
