In your desperate attempt to get after me, you totally missed the whole point of my post. Comparing a pipe that has been around for years, used by most builders in the industry and that has many different variations to a brand new pipe that has been out a year with only one type is RIDICULOUS.
That said, if Sniper claims to have made more HP than another pipe, it is because Gary and Jim have tested them and found what works best on their motors. That is not beyond the realm of reality at all.
So, if you're really wanting to get an understanding of the pipe, why not just call Gary and talk to him. Also, here is a dyno thread involving Snipers if you want to do some reading on them:

I will alert Gary to this thread and maybe he will come in here and offer up some more info.
