New mufflers that Twitter on overrun?

Reading the thread on mufflers reminded me of the wonderful and unique sound that the first Commandos with the reverse cone mufflers used to make on the overrun - that great twitter (tweeter?) or whistle. From memory we used to refer to those mufflers as "whistlers" and as I need to buy new mufflers I was wondering whether any of the numerous different mufflers on the market have replicated that sound? It would be wonderful if there was such a muffler available, as that sound was just so particular to the Commando.

Sigh ,yes, me too ,brings back sweet memorys...

That was the memory I had of my mates new Commando from 1969 and I would have loved to have found mufflers that made the tweeting sound when I done mine up in 2007 but they were not around.

I don't think I've ever heard it. I don't get around much.

I sadly don't get out much either :cry: , but I remember the sound well - My first Commando ride back in the '80s on a friend's 850 Roadster.
The twitter was very distinctive both when riding it and following it.

I haven't heard it recently either - I've got 4 different flavours of reverse cone available at the moment, but only one actually being used - I'll post back if any of them 'do that thing that they do'.

Got some black-caps too... :roll:

may work?

I have a pair of original Dunstalls decibels on the Interstate that have a great, throaty burble on the over-run. Maybe not what you are talking about, but i love that sound!
