How to Make My Exhaust Sound Louder

How to Make My Exhaust Sound Louder


A vehicle's exhaust sound is affected by four factors. The first and greatest is the engine size. The greater volume of engine displacement -- usually measured in liters or cubic inches -- the greater the exhaust output. Assuming the engine will remain the same, muffler type and construction, exhaust system piping, and exhaust-tip style may be altered or replaced to directly affect the overall sound profile of your vehicle. The replacement of exhaust system components with those designed to increase the exhaust output without sound dampening will make your exhaust sound louder.

Things You'll Need
Exhaust tip
Muffler
Exhaust pipe


Instructions
Replace the muffler with one designed to amplify the sound of your vehicle. Glass packs, straight-through exhausts and straight-pipe designs will significantly increase the sound output over a stock muffler. When you decide to select a new muffler type, consult a muffler shop or select a design that increases the volume of gas expelled through the muffler system without passing through sound-dampening chambers. Mufflers designed with limited baffles also can increase the sound output of your vehicle.

Add a sound-amplifying exhaust tip. Exhaust tips with dual walls, flared ends or large diameters may increase the sound volume of the exhaust output.

Increase the size of your exhaust pipes by 1/2-inch to 1-inch in diameter. This should be done in conjunction with replacement of the muffler to ensure that the gases are not constricted by the old muffler's diameter. The increased volume of gases allowed through your system will not only allow the exhaust gases to be ported from the system more easily, the greater throughput and pipe diameter will create a deeper tone and resonance in the exhaust system.

Connect your exhaust system with welded hangers. If your exhaust system is hanging from the vehicle with rubber mounts, the vibrations transferred from the exhaust system are dampened. Direct connection through welds helps ensure the vibration from the exhaust is heard in the passenger compartment.

How to Remove an Exhaust Resonator

How to Remove an Exhaust Resonator

An exhaust resonator on a car acts like a preliminary muffler. It mounts after the catalytic converter, and silences the exhaust an extra step before the muffler. Some people like this, but others prefer the sound of a vehicle with a bit more exhaust rumble. For them, one option is to remove the exhaust resonator from the system, which will make the exhaust louder in the process. This should take around an hour to do.

Things You'll Need
Jack
Jack stands
Tire iron
Reciprocating saw
Metal reciprocating saw blades
Gloves
Eye protection
Hearing protection



Instructions
Lift the vehicle up with the jack and put it onto a set of jack stands. Make sure there is enough room underneath the vehicle for you to work with the reciprocating saw.

Locate the exhaust resonator, which is mounted after the catalytic converter, and is typically just before the muffler. Put on your eye and hearing protection, as well as the gloves.

Put the metal reciprocating saw blade into the reciprocating saw. Cut the exhaust pipe 2 inches forward of the resonator and 2 inches rearward of the resonator with the reciprocating saw. Take the resonator out from underneath the vehicle.

What Is an Exhaust Resonator?

What Is an Exhaust Resonator?

Internal combustion engines usually make a lot of noise while they are running, and this noise can be annoying and exhaustive to your ears, especially when it is heard for a long period of time. Thus, mufflers were created to reduce the noise generated by the exhaust system. Exhaust resonators, meanwhile, further reduce the noise by making sound waves that cancel noises out.

Structure

A typical automotive exhaust resonator is made of a hollow steel cylindrical tube and is attached to the muffler of an exhaust system. This type of resonator is designed similar to that of an acoustic resonator, which creates an “exhaust note” that gives the exhaust noise a less annoying and more pleasant tone. The sound can be enhanced by means of adjusting the exhaust note.

Function

Exhaust resonators are usually add-on features in exhaust systems. They are placed together with the mufflers along the exhaust pipe and work primarily to decrease exhaust noise. The exhaust noise passes through the resonating chamber, which in turn tunes the sound to cause destructive interference in order to be canceled out by the opposite sound waves.

Availability

Being an add-on device, exhaust resonators are provided by aftermarket manufacturers and can be installed on muffler systems of internal combustion systems, such as automobiles and motorcycles. Some vehicles already are equipped with tuned exhaust systems with resonators, thus making the exhaust pipes capable of pulling the combustion products out of the chamber faster with reduced sound. Most aftermarket producers improve the exhaust tuners, as these help the vehicle perform more efficiently.

Advantages

Exhaust resonators provide a wide array of benefits to vehicle owners. Aside from reducing the noise from the engine’s exhaust system, resonators also enhance overall engine performance and smoother driving because more horsepower is yielded without wasting as much fuel. Noise suppression also helps in passing fuel emission tests, as the resonator prevents chassis rattling, an effect that usually leads to contaminated fuel emissions.

Support

Aside from exhaust resonators, catalytic converters also are part of the overall exhaust system to help the muffler perform its function of reducing exhaust noise. However, instead of canceling out each other's sound waves, their effect is to restrict the sound coming out of the exhaust pipe. Catalytic converters work hand in hand with exhaust resonators in reducing and suppressing engine noise, thus allowing the vehicle to achieve optimum engine and driving performance as compared with using mufflers alone.
