Go to a car meet and ask other owners to hear their setup? Videos do no justice.
I have the Corsa catback and no way in hell am I putting on a header. I've heard in person the catback + uel header and other components changed.. holy hell is it loud! Btw, there's a reason why it's so expensive. No drone at all, and that's what I was looking for when I was still shopping around.
I second what Mr. Impreza posted.
