Engine Drivetrain 1st Gen Cooper S Ireland Engineering "widemouth tip"

I emailed IE about this tip but have not heard back yet. Anyone know where I can get one ? I have to check with AutoX Cooper to see if they might have one left in stock but last I checked they were not keeping the IE exhaust around for supply reasons. Got a pic in this link :

I would be interested in a good shape used one also.
