Is a 3 Inch Exhaust Legal VicAdmin
The decibel scale measures the loudness of sound. The volume of the sound is calibrated via a logarithmic scale, but we don`t really need to know the math behind the science. Suffice it to say that we have a loudness measurement system, and we also have several reference points that illustrate important points on this diagram. When you hear a normal conversation, you feel a volume of 60 dB (decibels). A crowded party increases this number up to 70 dB. At this point, you really recognize sound as an irritant. It`s a piercing, roaring sound that breaks your concentration. Now imagine going from the 90 dB threshold to a 120 dB noise source. In this scenario, you`re stuck together and covering your ears during jet takeoff, or maybe you`re locked in a steel mill, a place where hearing protectors are mandatory. With these references in mind, how loud is it when a performance-optimized car exhaust emits its most guttural roar? Legal decibel levels vary from country to country. Nevertheless, a secondary market enthusiast should be aware of this threshold, even if it is different in the next state. Finally, the legislator punishes the owner of the car if the laws are indiscriminately broken.
Have the exhaust system loudness checked. Use your own sound level tester or shop inspection test to avoid a violation. By the way, a damaged exhaust system can easily produce prohibitive amounts of noise, so bring the noisy vehicle to your exhaust shop before getting a quote. Let`s answer this last question before we go any further. An aggressive exhaust system can easily emit a roar of 110 dB. That`s enough noise to set off even the smartest car alarm and send the local dog into hours of protest. We need to do our part to reduce those animal tones, even if they make you happy. To achieve this performance, the chosen aftermarket exhaust system must shape and minimize the noise intensity envelope while expelling back pressure from the engine. What exactly are these legal limits? The EPA (Environmental Protection Act) requires a limit of 90 dB, although motorcycles are allowed to reach a threshold of 94 dB.
Assuming the car is less than 90db, you can have any exhaust as long as it has a cat. Please note that if you end up inserting a silencer, it will record that you are using a silencer and you should always leave it on from that point on. Benno even makes 4-inch exhausts quieter than a standard exhaust A deep sense of satisfaction creeps through your vibrating bones when your exhaust system cracks, but that happy smile quickly fades when you enter a residential neighborhood. Obviously, your car`s exhaust generates too much noise. This violates a local ordinance and disturbs your neighbors. Let`s calm down on this street full of howling dogs and angry residents by making sure your exhaust noise level is legal on the street. Well, I recently received a nice letter from the EPA saying my exhaust was too noisy. When you go to the test, is it acceptable to have an exhaust system as long as it is less than 90 db? Are there any restrictions on the exhaust system you can have without the amount of dB it produces? Any system is fine as long as it does not exceed the 90 dB limit.
But there are some guidelines, I believe you need to have a cat and 2 silencers, one under the car in the front and one in the back. Be aware that EPO and the police now use digital cameras to keep track of your behavior, I received 2 fines of $511 each. However, both times I was stopped by a police officer wearing a portable database tester. For the record, it was PETTET. Laughing out loud. Replacing the rear muffler with a stocky muffler is simply no longer enough. Sigh. Do what most people do, swap it for a sticker. Much easier. I`m pretty sure you can`t use a muffler at all unless it`s fully shrink-wrapped, look at the vicroads website, it covers everything in the change guide. Just do a search.

I went to Chaser`s Tuning this morning and they can install a muffler somewhere in the middle of the 3 inch pipe. No wonder it was so strong, it was just a straight pipe.
