But in older cars with archaic exhaust systems, removing the muffler may result in noticeable performance gains at high engine speeds, not to mention a louder and more exhilarating exhaust sound. How Mufflers Work. Inside a muffler , you'll find a deceptively simple set of tubes with some holes in them. These tubes and chambers are actually as finely tuned as a musical instrument. They are designed to reflect the sound waves produced by the engine in such a way that they partially cancel themselves out.
Is it illegal to remove silencer from exhaust? All exhaust silencers must be maintained in a good and efficient working order. You will be breaking the law if you remove a silencer or make any modification that would make that vehicle emit a noise louder than the original exhaust before it was modified.
What is a silencer delete? A muffler delete is the process of removing the muffler from the car's exhaust system. The muffler is the device responsible for dampening the sound emitted by the car because of the vibrations and the heat created by the internal combustion engine. Can you hollow out a muffler? Putting on a straight pipe would make more sense then hollowing out an HKS straight though.
The proper way to make a sleeper exhaust is to cut open like picture above and remove all inards. Does removing cats make car louder? Vehicles that have catalytic converters can only operate with unleaded fuel, but when you remove them, you're allowing yourself to put a more efficient and high performance gasoline in the car. Better sounding exhaust. If you remove your converter, you're giving your car a louder and more distinctive sound. Do muffler inserts work?

A chambered muffler is less restrictive on the flow of exhaust gases, giving minimal back pressure and so this design is found on performance vehicles and in the aftermarket. It has less of a silencing effect on the exhaust and gives a deep rumbling sound. The original design of muffler is a straight through muffler. It's seen on hot rods or at the side of classics like the AC Cobra.
In this design a perforated pipe runs straight through the muffler, wrapped in sound absorbent fibre-glass like rockwool. The idea behind this muffler design is the same as filling a room with soft-furnishings to reduce noise.
As the sound waves travel through the pipe, they will escape through the perforations where they are reduced in two ways. A straight-through muffler creates almost no back pressure - in fact a well-engineered straight-through muffler can improve the flow of exhaust gases compared to a straight pipe.
But their noise reduction is limited compared to the other two types and they are not generally found on production cars. Mufflers typically fail from corrosion. Like all exhaust parts, they have a hard life being exposed to hot corrosive gases on the inside, and the weather on the outside.
Water is a byproduct of combustion - it comes out of the cylinder as hot steam. When a engine starts the exhaust system is cold and this steam will condense into water. Since the muffler is furthest away from the engine it takes the longest to heat up.
Water will build up inside until the muffler warms up and the water is boiled into steam and goes out with the rest of the exhaust gases. If a car makes only very short journeys there is a risk that the muffler never warms up and water builds up inside, rusting the muffler from the inside out. Mufflers will often incorporate a pinhole at the bottom to drain out any built up water. The reality is that this is probably why my mum destroyed so many mufflers on her Lada, but it's much more satisfying telling her that she's a speed demon and can't help herself but launch off every speed bump she sees.
Vehicles produce noise from a lot of places: - The whistle of the intake system sucking in hundreds of litres of air every minute. In Europe, the current rule is that cars produced since can make a maximum sound level of 74dB. Cars for the disabled are allowed another 1dB and bulletproof vehicles get an extra 2dB. That's a big reduction. The most important thing to understand with mufflers is that we are dealing with two different things: - The exhaust gases are physically flowing through the exhaust.
