Savages are noteworthy on Independence Day.

"He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions."

The Declaration of Independence, July 4, 1776

I suppose a modified exhaust could be considered something of a domestic insurrection.  

Also of note regarding the primary author of the DoI, "Many aspects of Thomas Jefferson's home, work, and personal tastes were influenced by Italian people and culture."
