I didn't really want to make it too loud since we ride a lot with groups or with the whole family on board. I've heard others that are pretty loud, but this exhaust really isn't too bad. I'm looking to improve performance with some upgrades since we are pretty loaded with people, accessories, and gear. I haven't tried it with the quiet cores yet, but it should reduce the sound level a bit. My daughter was in the front seat with me and we were able to talk and she didn't complain about it being loud. So far I'm happy with it.
