Pac Brake Hissssssss

I installed my Pac Brake today and everything went smooth. My question is when I turn on the exhaust brake I get a loud hissing sound. I know all the air is forcing itself through the small hole on the butterfly but this hiss is loud. I checked for leaks and can't seem to find any. I searched and found that other members have a whistle sound when brake is engaged but this is a loud hiss not a whistle. Maybe it's b/c the truck is 4in and straight piped? Any thoughts?
