As a general rule, the louder the bike the smaller the d***.
This rule can be extended to include pickups with large wheels.
If that's the case, then my children are the product of immaculate conception. My bike is beyond loud. I run SEII's and I've pulled the baffles and redrilled every hole with a 3/8" bit. It sounds like a Harley is supposed to sound.
You get a grant from Bwarney Fwank to study this?
