Honestly I went with the muffler deletes and I was expecting it to be a lot louder. It's quiet at idle and only loud when you get on it hard. On the highway, very very mild drone over 75mph but that's it.
As for the 4" mufflers, check youtube, there are tons of video clips with inside and outside samples. The build quality is great and they are pretty cool guys.
