There's no baffles really, it's just a "cigar" filled with wool, surrounding a perforated pipe.
You need to cut the silencers open to remove the wool if you want to nig them up.
I've heard old flatheads with emptied out cans and they sound mighty fine without being obnoxiously loud.
The flatheads in general sound frankly beautiful.
