The Hardly Able-son riders I know say they yank the baffles out to be heard
on the roads.
Kinda like a safety feature since car drivers have always had a hard time
seeing motorcycles.

Oh yeah, it IS Friday!
Heck, why not four Briggs and Stratton engines, aren't they the same
technology as Hardley Davidson? Or the V-twin Maytag washing machine
engines of years past? Only idiots with no brains (or respect for
others) yank the stock HD mufflers to 'make the bike kool'. Not
referring to anyone in particular, but it is quite a hoot to see all
these 'badda$$' bikers who think the are Easy Rider or Heck's Angels.
