The loudest exhaust tip is the megaphone style. Though not commonly seen today because of styling changes and they are not in vogue anymore, they can dramatically make certain exhaust louder. They work the same way a musical instrument, (trumpet, tuba, trombone) work. Ever seen a cheerleader use a megaphone? They work off the same principal. Taking the wave length (sound) and tuning it to a amplified level. This may be a oversimplified way of explaining but choose wisely of which you use. Each size and construction can change the sound wave length as well as the structure of the exhaust leading up to it.
