If you're looking for "just barely louder than a Honda Odyssey minivan at idle," NPP is for you.

If you're wanting people to notice your ride from 3 blocks away? Corsa, Borla, B&B, Loudmouth, etc. While I'm clearly exaggerating about the Honda Odyssey, NPP will just not get it done. It is only slightly louder than the plain ol' mufflers GM slaps on these cars.
