Long tubes louder?

Long tubes will be quiter at idle, and cruising throttle

However if you lay into the throttle, they will be alot louder.
The longtubes really open up the sound at wot

When I put shorty headers on mine. It got louder than what my long tubes. Plus I gained some power

Seems odd, what is your combo, and how much power did you gain?
What size LT's and what size shorties?
What intermediate pipes did you have with the 2 different header combos?
Typically, Long tubes will make more power than shorties, especially at lower rpm.
