So you are saying Since I have the Kazuma I am ricer??
who said that?
the kazuma is a racing exhaust. it's loud because theres not a lot of restriction to airflow and it gives great gains.
you're not supposed to drive with it on public roads anyway..if you drove down my street with it i'd say 'ricer!'
at a racing track (where it's only supposed to be used) i'd say "wow, he's got kazuma!"
