Maybe 10 HP at best to freewheel the A/C and run the alternator, water pump, and steering. Please cite a source to back up these claims.
This 2013 exhaust is bound to produce more peak horsepower, how little is to be seen on dyno, probably not felt in stock form. This system will probably respond better to aftermarket headers compared to the regular exhaust.

The test was done in 09 when the 5th Gen was first released. It was done, I believe by Hp TV then broadcast on the Speed Channel. They actually setup a LS3 on a engine dyno, to test the actual output without all the belts and pulleys attached.
There is a writeup in one of the performance mags online, just don't remember which one it was.
