[avalanchejf9]

Which is the best brand?

 

[bmrrwolfe]

Personal preferences.
Some prefer Flowmaster. 40, 44 or 50?
Some Magnaflow.
Others just like Thrush or Dynomax mostly for the price

You are aware that in FL it's illegal to mod your exhaust, right?

WHAT THIS MEANS FOR YOU
The law states that you MAY modify your exhaust system. You may not modify it in such a way that:

-You remove any of the exhaust components
-It emits excessive pollution
-It is louder than the stock muffler



This is not a gray area. There is no fighting this. You must adhere to these guidelines or you are liable for a ticket. If your exhaust is aftermarket and even .0000001dB louder than stock you are liable for a ticket. If you are missing a part of your exhaust system you are liable for a ticket. Shops, by state law, are not to equip your car with an aftermarket muffler which increases your exhaust noise for operation on the public roadways. Replacement exhaust components must be OEM or aftermarket and as quiet as OEM.

Just because your aftermarket exhaust is stamped '50 state legal' does not mean you cannot be ticketed. You most certianly can. I do not claim to be an expert on what they mean by 50 state legal, but I can tell you that it is NOT legal to operate a motor vehicle with an aftermarket exhaust that makes it louder. Period.


There is also nothing in this statute which says the officer has to use a decibel meter to measure your exhaust. It does not have to be louder than a certain decibel to be illegal. It simply has to be louder than stock. While the law instructs specific areas to set their own methods of measurement, it does not take a decibel meter to figure out if an exhaust is louder than stock.

Just throwing this out there, there is no way cops enforce this.
I've been to Florida plenty of times and probably 1/4 or 1/5 cars, Jeeps, trucks or motorcycles are modified, most of which have a louder then stock muffler

Unless they WANT to find something to ticket you for; which is usually the case.

^^^True...

Just don't floor it past a cop, that should be safe.

 

[avalanchejf9]

Yea i have never heardd of anybody getting pulled over for that. The guys at my school mod the crap out of their cars! But yea i'm thinking of the flowmaster 50. But i hear magnaflow is good also.

 

[avalanchejf9]

But thanks for the heads up hoosier!

 

[JeepINgeek]

well. the KJ sounds badass with no muffler. so you could just go cats only.
or you could spend 300+ on a pre manufactured one

or just throw a sub 100 flowmaster or whatever on it..

Hey HJ

(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.

ONLY THING THIS MEANS IS THAT YOU CAN'T JUST CHOP YOUR MUFFLER OFF.
What about a Neon SRT4? They don't have mufflers at ALL. That would make those cars illegal to drive in Florida by your logic.

If the SRT4 came off the assembly line without mufflers then it is in it's originally manufactured state right?

TBJ, your point is moot.

 

[ThunderbirdJunkie]

Oh.
Derp

TBJ, your point is moot.

Thank you for using moot correctly and not typing mute. It's just one of those things you know...

Don't shoot the messenger, just posting up what FL laws are...

 

[Clyde Frog]

"Best" brand is generally personal preference. There isn't a crazy amount of a difference between Magnaflow and Flowmaseter (which is pretty much the only two anyone gives a crap about).

Talk to your local muffler shop about what kind of set up is in your price range and go from there.

 

[family KJ]

^^^True...

Just don't floor it past a cop, that should be safe.

We don't even have to get anything inspected in Florida on a yearly basis...Do whatever you want...You are not driving an 80's camaro, you got a Jeep that may be a little loud....You will be OK.

 

[avalanchejf9]

haha yea i think i will..but yea thanks clyde, i think i might go with the flowmaster
