I never heard to one be referred to "snail" but I'm pretty sure you are talking about what is now called CT outlaw pipe setup.

Its a cool looking pipe and sounds great, Its mainly for flat track as far as I know.

I like the idea of the all business short out of the way setup, But kinda feel it would kick up to much dust and maybe even making bit of mess with the oil spoodge?

Not sure never been around one long enough to see only seen one once like yourself, maybe someone on here uses one would be good to hear more feedback about the outlaw...
