According to FL state law, any modification to an exhaust is illegal. HOWEVER, subsection D of the same statute you're being written up states that it's illegal when the sound is made louder than stock. As no cops carry decibel readers, they cannot site you for a car being louder than stock. They cannot say on paper that your car is louder than a stock integra without burden of proof. Just mention that next time you're pulled over. You'll get a warning.
