I would like to hear what the official stand is on this one from the state police in a press conference announcement. This appears to affect all motor vehicles with emphasis on motorcycles. I have heard so many conflicting stories on this "straight from a cop's mouth".
The wording of the new law appears to totally override the 95dB rule in the previous "exhaust law". It does so by stating you can't have any exhaust louder than OEM. SPT users should be able to get away with this as it is an "as sold" component on the car. If they give you a ticket for it, I would contest that. Anything else is fair game for them to toss you a ticket.
I swapped my cat-back to stock (left the 3" dp) and really can't complain as I didn't lose an ounce on the butt dyno. In fact take-off torque is increased with the added back pressure of the stock setup, and as a bonus I won't go deaf by age 25.
As for the subjectivity of this law, the verbage leaves total control to the sensitivity of the officer's ears.
Lets hope this one doesn't last long. It may not seeing as how sloppy it is worded.
