ive never heard the other 2 pipes that you have listed here(in person anyway) im partial to the troublemakers..they are nice and loud and i felt a good boost in performace when i put them on...besides that they look nicer than the others...IMO
I like the V&H Straightshots. Not too familiar with the shortshots but my guess is that they are louder than the Straightshots. Probably for the deepest rumble, Rinehart's are the way to go.
When people make videos with their bike idling in the garage it always sounds louder and better to me but doesn't really give you a true representation what it sounds like out in the open without garage walls affecting the sound.
