Free flowing exhaust is generally a performance (mainly power) improvement for an engine. The trade-off is free flowing generally means louder. However, the tuner-nerd crowd (a lot of small engine imports) aim less for performance improvement and more for just loudness.
For a lot of people, attention is hard to come by, especially positive attention -- so they settle for negative. Loud music, loud cars, whatever they can come up with to say HEY! LOOK AT ME!
They run the loud base to prove that they are a&&holes. They run loud exhausts to prevent restriction to the exhaust gases so that more air and fuel can be put into the engine.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
