I wanted the ATG as well but they send it with SA postal service so it takes about 21 days to get here in London (have a 30l backpack on the way) and that will be too late for my trip so I had to go with these but I don't regret it one second.

They have a heat shield that you fasten to your exhaust. I had to order two because my MTC can touches it on both ends. I also ordered the pannier rack version, it has a hard backing on it just in case I do pick up a rack at some point.
