There is an attachment that details the exhaust for the T model. It indicates a muff over the muffler but only one and I don't see any scat tube connections.
You could try to duplicate a normal aspirated system on your T model but it will require a field approval for the STC as I don't think there is an STC out there. I could be wrong so you might want to give Don Neiser a call or Owen Bell as they may know.
Good luck
