The Ins and Outs of Harley Exhaust Systems

The Ins and Outs of Harley Exhaust Systems

Most of us like to turn heads with our bikes and the exhaust is a big part of that. A cool looking exhaust system can really enhance the appearance of your motorcycle. Plus the distinctive throaty roar of a Harley-Davidson engine comes from the exhaust.

But there is more to Harley exhaust systems than gleaming chrome and bestial growls. Understanding the function of your exhaust lets you choose the best one for your bike.

Dealing with Emissions

The full Harley exhaust is designed to deal with the output of an engine, dealing with environmental, aesthetic, and legal issues.

The converter is designed to change harmful chemicals in the emissions into something less damaging to the environment. It uses a catalyst to convert dangerous gasses, including carbon monoxide and unburned fuel into carbon dioxide, water vapor, and other innocuous compounds. Reducing harmful emissions is not only environmentally friendly - it is also required by the EPA.

The muffler control sound and sparks. Although many Harley owners like the roar of their engine, many communities have noise ordinances that limit how loud your bike can be. Mufflers don't necessarily just suppress sound. They can also be used to control sound to get the noise you want from your bike.

Performance Enhancement

Your Harley exhaust system has a strong effect on engine performance and power. A clogged or poorly designed system restricts the flow of exhaust and reduces engine efficiency. Consider a path from the gas tank through the engine to the exhaust. If any part of that path is restricted, the whole system slows down and that means less fuel to your engine and less power.

Most people understand that a clog in the fuel line reduces power but may not realize that a clogged exhaust can do the same. Clogs aren't the only problem. An inefficient Harley exhaust restricts the flow from the engine and that creates a backup which cuts performance. Well designed systems with smooth curves rather than sharp corners allow the exhaust to vent more easily and the engine to run better.

High vs. Low Mounting

Where you put your exhaust, a high vs. a low position, will generally be determined by the bike's use. High-mounted Harley exhausts are used for bikes that will be used on trails and off-road. These bikes get a lot of dirt and water coming their way and the pipes are mounted high to keep these contaminants from getting into the exhaust and clogging it.

The problem with high-mounted exhausts is that they aren't very passenger friendly. Street bikes are more likely to carry passengers and don't need the protection of high mounts. These motorcycles are more likely to opt for low-mounted exhaust systems.

Choosing the right exhaust system is key to both the look and performance of your bike so consider all of your needs before making your choice.

Understanding A Marine Exhaust System

Marine exhaust systems are an important and often neglected engine of a ship. Most ships have a system of "wet" exhaust. The outlet for the exhaust gases from the exhaust manifold - the salt water is injected into the column. This mixture of gas and water is then passed through a series of curves to it from the boat, preferably in the back.

Exhaust fumes mixed with salt water to create a highly corrosive compound. This is why exhaust systems are often non-corrosiveComponents such as nitrile rubber reinforced hose (brown - not green - stripe), galvanized steel, fiberglass or plastic. The purpose of these components, which vary in size and shape depending on the size of the engine and the layout of the engine room is to prevent the engine hydraulicing. This occurs when an engine full of salt water that entered through the exhaust and can cause considerable damage if left for more than two hours. The water enters the exhaust gas to swell in the tail and armDrain design. In some sea conditions, such as by sea, the water can again be forced to exhaust when the engine is not running. Drains poorly designed, that water will flow back and fill the waterlock / muffler box then the hose in the exhaust manifold, exhaust valves and combustion chamber. With the engine full of water can not compress the engine crank over, it is not like water.

Exhaust System

You will know that your engine is if you do not turn around hydrauliced ​​-usually after a long period of sailing - and removing the starter and make sure it works. To remove remove water from inside the combustion chambers, first of all injectors, crank engine blowing over the water, replace vent injectors, injector lines and restart. Then leave the motor running until exhaust fixed.

Check that the mast is not coke up or corroded - a common problem. To check the exhaust riser remove the drain hose from the riser (often a difficult procedure)and look at the line, to see if it is the accumulation of exhaust / salt restricted. When building the riser is too large to be removed in order to check the engine side of the line. Coke can be scraped off as a short term fix although often the riser must be replaced. There are aftermarket systems which vary in quality. Make sure you fit the right model for your application.

Make sure that the water-lock is low enough and large enough to hold all the water in the exhaust system. There is aA gooseneck or central vertical loop in the vent pipe to rely on the mirror? It is a siphon break and function - without valves leak?

Exhaust is toxic and can cause motion sickness and headaches. Replace defective components immediately. Use double hose clamps on each joint or, preferably, super, the style of concrete drain bolt, if necessary. Hot sections should be insulated with fiberglass tape to prevent burns.

Asbestos Warning delayed. Many larger vessels andMarine engine installations had exhaust systems that were lagged with asbestos tape and rope. Asbestos was common in older boats noise.
