fyi, EVERY VEHICLE EVER seems to have more pep once you can hear the motor.
ears are notoriously poor dynamometers.
and honestly? what's more important? gaining 2 horsepower, or THINKING you've gained two horsepower? i don't discourage people from buying K&Ns or louder exhausts for cars or for bikes, but those who do so in the quest for any meaningful power are setting themselves up for disappointment.
perception is everything, unless you were trying to shave 5 hundredths off your e.t.
glad to see two hondas in your garage. those old oil stains must be from a previous, harley/dodge kinda homeowner.
