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. 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.
How to Troubleshoot a Car Exhaust or Engine Noise
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.
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.

Step 1 Replace the muffler with one designed to amplify the sound of your vehicle. Step 2 Add a sound-amplifying exhaust tip. Tip If you wish to have a louder exhaust, but not in the passenger compartment, replace direct welds with a free-hanging suspension system with rubber connections.
The vibrations from the exhaust system will be dampened at the point of connection. Sound-dampening insulation, such as sound mats, also can be used to dampen the sound heard and felt in the cabin of the vehicle. Warning A size increase in the diameter of the pipes may initially increase the performance of your vehicle due to unrestricted exhaust-gas flows.
However, as the size increases beyond acceptable ranges, which differ depending on the vehicle's engine, the horsepower and torque may be decreased.

Photo Credits exhaust pipe image by ABy nature, the combustion engine is supposed to make noise.
Anytime you have a controlled explosion occurring multiple times every second, there are bound to be some sort of racket coming from the engine compartment. Although most of today's advanced exhaust systems are designed to muffle the road noise, there are times when they break, wear out or crack, causing a noisy engine or exhaust situation that typically is an indication of a potentially expensive repair.
However, not all noises are the same; or are caused by similar mechanical component failures. The fact is that there are several different types of noises that are made; each of them contributing to a different mechanical failure.
In order to correctly identify the noises and troubleshoot their primary source; we've taken the liberty to document a few of the common sounds that a damaged component will make and what typically causes these noises in the sections below. Description of this sound : This noise is associated as a vibration or buzzing sound; similar in many ways to the sound that a window or portable fan makes when it is activated.
Some of the common causes of this type of sound are attributed to belts, pulleys, or belt-driven components. What's the cause of this sound? A whirling sound which changes pitch or volume based on the engine speed is a typical sign of engine related issues. Parts that cause this sound are belt-driven accessories, or the actual belt. Some of the most common component that will make a whirling sound includes:.
These sounds may be caused by loose belts, bearings that are damaged inside the pulley's or brackets or the pulley itself. In most cases, if the belts and pulley's are in good shape, are tight and not the source of this type of noise, the water pump is the most likely candidate.
Description of this sound : Essentially, the hissing sound is the sound of vapor or steam escaping a pressurized source. The gurgling sound is typically associated with boiling water and a sizzling sound, similar to that of hot bacon being fried on a griddle. In many ways, these three sounds typically are attributed to the same source; an overheating engine or coolant system. When you hear the hissing sound, it's usually attributed to steam that is leaking from the radiator cap, the overflow tanks or a recently created hole in any part of the cooling system.
As the coolant begins to heat above degrees, it starts to boil, which when contained in an enclosed system like a radiator will develop excess pressure. Once this pressure gets to a certain "boiling point" it will also make a gurgling noise.One of the most ignorant components of any vehicle is its exhaust.
Well, it could be signaling us about some major issue inside. Exhausts generally create the deeper and softer sound, but an insecure and broken connection of the exhaust system, right from the front to the back can distress the normal sound. For that matter, we have come up with the best exhaust tip for deep soundso that you never have to worry about this entire system that connects from the engine box to the backside of your car.
A deep sounding exhaust is an apparent clue of the smooth working of the engines. Undoubtedly, the exhaust system works the hardest. After all, it functions to control the noise while directing the smoke away from the interiors of any vehicle. But how to make your car sound better? Are there any maintenance tips that need to be followed for that matter? Here is the best way to maintain that deep soothing sound of the exhaust system of your car:. Maybe the muffler is not a proper working condition anymore.
Maybe it is the time to replace it with a new and powerful one. There comes a time when the original muffler does not have the power to work like the time when it was installed. In that case, installing a new one would be the best exhaust tip for deep sound. Just get one that is more powerful to bring back the deeper exhaust sound. Old pipes may hinder the smooth working of the entire exhaust system. Also, the exhaust will not be able to deliver its full potential until it has those small sized pipes.
Small pipes can obstruct the smooth flow of pressure and temperature in this system. Installing brand new quality pipes will certainly result in better performance of your vehicle as a whole. But beware of those fake exhaust pipes that can make your car look cheap.
Go for the best quality pipes, always. Constant inspection of the mounts for the exhaust system is important. The exhaust system mounts uses a specific type of rubber to hold those pipes together.
This rubber loop even helps the pipes to move, as needed. With the usage of the vehicle, this rubber loop may fall apart or may lose its original place. For this reason, a constant eye on the exhaust mounts rubber loops is a must for getting that perfect deep sound from the exhaust system.
Hold the muffler and shake it a bit to see that it is on the place or not. If the rubber loop is falling, it is the best time to replace it with a new one. So, replacing the old exhaust system rubber mounts is also one of the answers to how to make your car sound better. Another way to attain that deeper sound for your exhaust system is by unclogging the exhaust tube correctly.
Most of the times this blocked tube is the culprit to make the engine and exhaust lose its power and performance. This further hampers the backflow into the entire exhaust system. Using the mandrel tubing to clean the tube will make way for fresh air. Well, if you want the exhaust system of your car to run in its best shape for years, maintaining and constant check on it would be the best exhaust tip for deep sound.
Also, keep getting it checked by reliable and trusted professionals to keep that deep exhaust sound going on.

They can also be an annoyance to yourself and others. Your exhaust system could be loud either because of alterations intended to increase the vehicle's performance, or because of failing equipment.
Regardless of the reason, there are permanent as well as temporary ways to quiet an excessively loud exhaust system. Make sure the catalytic converters and the mufflers are working properly. If they become damaged or have been bored out to increase performance, they can be very loud. In most cases, the check engine light will be on if the muffler or catalytic converter are damaged or altered.
Change the mufflers. On most vehicles there are four bolts which hold the muffler onto the tail pipe. If you have dual exhaust, there will be two mufflers. Glass pack mufflers tend to be very loud, but also tend to allow the best airflow. Reactive mufflers are included on most vehicles and are much quieter. Changing your muffler to a quieter one might affect your performance, but can make your vehicle quieter. Replace your tail pipes. Larger diameter tailpipes tend to be louder than smaller diameter tailpipes.
Often larger tailpipes are added to increase performance. If you don't want to reduce your tailpipe size, consider a crossover tailpipe. A crossover lets air travel between two exhaust pipes, which causes the pressure to equalize between the two pipes. The result is higher performance and less volume. If no alterations have been made to your tailpipes, this step will not be appropriate.
Shove a wad of steel wool into the tailpipe. The wad of steel wool should go in as far as the holes that were drilled. The steel wool will work as a damper to absorb some of the sound without a dramatic effect on the vehicles performance. Thread the wire into one hole, through the steel wool and out the other hole. Twist it around the tail pipe to secure it.
