When you finished testing you can have baked potatoes for lunch :-)
It looks like it might be hard with the Remus to fit up a valve kit as one of the tips have to be cut right back to fit a valve kit, you would have to check locally.
i thought that the actual design for the exhaust changes when adding a valve system. one of the tips is usually a straight pipe, this one will have the valve. the other one will have a different design with more restriction than the valved tip hence being quieter when the valved one is closed.
