Most of the other headers are crap. The money is in the Megan. Another buddy of mine just put the megan header on his car and went from 199 to 215.5 with a vafc tune, megan tp, Invidia V2 and comptech cold air box.

 

Also, I have heard that the megan header makes even more power with the 70mm exhaust. Won't know for sure until someone does a dyno though.
