It was an automatic. I never have seen it make a good pull. They tried it in the open class a few times that i saw it pull, but they never could get the transmission to shift or put any power down. It was weird. They may have the bugs worked out of it by now though.

Twin turbo, individual stacks
The exhaust should be going behind the truck due to forward movement(unless there is wind) and the air won't be 1600 right there, the turbo will help cool it down. Warm air though for sure.
