Need LOUDER Exhaust...

i need the loudest exhaust imaginable...
why?
i'm 16... i have no respect for society... and i need attention.
not that i don't get chicks... i kAn.
but why not go all out and be heard?
exactly...
today i heard the loudest exhaust on a civic ever. not a farter but a REALLY LOUD deep exhaust. very nice. it rode right past me as i was walking through the school parking lot and i almost had to cover my ears.
any clue what the guy had?
or what a really loud one might be called...?
