This is one of the earlier videos... The volume in this may be a little louder due to the lack of Cats... but it should be fairly similar.

Tone on the slip on might be a little better due to the resonating properties of the catalyst though. Take it for what it's worth.

My apologies, the site won't let me embed this video for some reason.
