The intakes are loud enough that I can hear them above wind noise at 150+ mph. I wonder if the sound they produce is exempt from Federal noise standards?

You're not kidding. I thought I was crazy until I realized I really WAS hearing nothing but intake noise when I was about 6000RPM on my K6. Even with an aftermarket slip-on, I can barely hear the exhaust over the intake at the same RPM range. It's really not unpeasant though, and I doubt would garner a lot of complaints on the "annoyance" scale.
