Would the dual cats actually reduce emissions? They might never heat up
enough to do their job.

On one hand,I like to modify my car as much as the next guy.
OTOH,I really dislike the noise coming from some cars and motorcycles.
Especially late at night,when they wake me up from a solid sleep,even with
windows closed,right thru the walls.

I honestly do not believe there -has- to be a "objective
standard",especially as measuring it on a passing car presents problems.
Maybe just a "reasonable man" standard.

Also,police already are unwilling to give citations for most
infractions,getting them to write up noisy cars/trucks/MCs is fantasyland.
And most states no longer do vehicle inspections where such things would be
caught.
