Ok so Tuesday, I backed into my brother's driveway to pick up my brother's boat to go fishing. He lives in a subdivision like and the houses are less than 4 feet apart. I picked it up and drove off and later that day I came back and his neighbors were outside so I asked them and their 2 little girls who are autistic if I woke them up and they said yes.

Right now I have dual Dynomax Turbos with gutted cats (hate the gutted cats) and I'm looking into getting something a little bit quieter like Flowmaster 50 or 70 series which I've heard isn't loud on the outside and inside isn't bad. But my quest is the cats what should I get? I've heard Summit has some good ones or I can go to the junkyard and get some.
