Reverse cone exhaust

[red ghost]

Do these still have a baffle inside?

[poose]

I have a reverse cone clubman on my scoot and I would say from the sound of it that theres not much of a baffle in it can hear it coming from miles away ! From a conversation I had with AF a few weeks ago think there is a baffle in but not much of one.

So does the 'reverse cone' actually work like a reverse cone?

Is there any science in these pipes?
