this. that is way too big unless they have some sort of forced induction and/or running fuel rich

probably a power loss unless they modified the intake system

On turbo cars, exhaust tubing typically will be larger than NA engines to help the turbo breathe. Although it does seem large I bet there's a good power gain on the top end. I'd really like to see some dyno#s.
