There actually isn't an "exact" amount gained from the headers. Every car is different and every car will respond differently depending on whether or not the car is stock, the weather, or your elevation. To know for sure, you would have to do before and after dyno runs.

With that said, you should be able to see at least a 10whp gain, if not a little more.
