Since these things take the place of the mufflers in the exhaust system, so in effect there ARE no mufflers now on the car when these are installed, are they actually LEGAL on the street in Florida?
 
I believe its a Federal law that mandates all cars have catalytic converters. I don't think there is a regulation about mufflers, as long as it doesn't break your local noise ordinance. I'm sure all of our cars do that though. You would think if it were illegal, SLP wouldn't be able to sell the Loudmouth exhaust and B&B wouldn't be able to sell most of theirs. They don't have mufflers.

It wouldn't surprise me if it were illegal. We're talking about a state, at least my county anway, where it's legal to sell fireworks, legal to buy fireworks, but not legal to shoot them all off! Only some are legal.
 
From an earlier post re: exhaust systems. You'll find the answer here.

I just saw in another Legal Issues post you submitted the statute used around here for modified muffler cites was quoted in 316.293 (5)b FSS. No need to post my pics because this is the exact same thing I saw in the 2006 book.

(5) NOISE ABATEMENT EQUIPMENT MODIFICATIONS.--

(a) No person shall modify the exhaust system of a motor vehicle or any other noise-abatement device of a motor vehicle operated or to be operated upon the highways of this state in such a manner that the noise emitted by the motor vehicle is above that emitted by the vehicle as originally manufactured.(b) No person shall operate a motor vehicle upon the highways of the state with an exhaust system or noise-abatement device so modified.


Kind of general, so it covers anything "louder than factory".


This is my take on the entire matter:
The way the manufacturers get around it is the "off road use only."

Also, when they say they are legal, they're referring to CARB or emission compliant systems.

Noise is both, local, county, state and federally regulated.


Drive safe,
