Muffler options

I have a cousin who is mostly a sissy. I had him buy the exact same mufflers I use and he says they are too loud for his pussified self.

He wants something different. I'm saying Hooker aero chambers look like the next best option. I don't want to hear hime whine. So what says FABO?? He says he wants it throaty, but not too loud and it can't drone.

Am I on the right track with the hookers?
