Depends on what your sister means by "pretty quiet". I run Flowmaster 3-chamber on mine with dual 2" exhaust and tri-Y's on a 302. It's certainly much louder than a stock dual exhaust. I like the deep rumble at idle and the roar when I step on it, but I'm currently deep into a midlife crisis trying to recapture my youth. If your sister wants to hear the stereo clearly at freeway speeds, you might want to consider a quieter exhaust.
