Pros and Cons of a Dual Exhaust System
Before you install a dual exhaust system, you should understand its pros and cons. First, you must identify what you are looking for in a vehicle's engine and can then decide about the exhaust system performance.
What is a Dual Exhaust System?
Every vehicle comes with an exhaust system, single or dual, that gets rid of burned gasses from the engine to keep it cool and running well. The exhaust system impacts the vehicle’s performance and engine operation. A dual exhaust system uses two exhaust pipes to carry out the engine exhaust. It usually consists of a muffler to minimize noise, a manifold to collect exhaust, and a catalytic converter to make the exhaust less toxic.
Pros of a Dual Exhaust System
Increased Gas Mileage: The engine in a dual exhaust vehicle runs more efficiently and with less effort. This is achieved when there is less engine back pressure, and thus less wasted energy. The more efficient the engine, the slower the rate at which the fuel burns, which means that you don’t have to use as much fuel as you would with a single exhaust system to go the same distance.
More Engine Horsepower: Burned engine exhaust gases exit the combustion chamber faster and easier than a single exhaust system because it has two exit pipes instead of one. This increases the engine’s horsepower, which means that the engine is more powerful than a single exhaust system.
Cooler Engine Temperature: The dual exhaust system helps the engine run more efficiently, and therefore, it is cooler than others. This lower temperature and operation efficiency ensures that the engine will last longer than it would in other vehicles.
Deeper Exhaust Sound: A vehicle with a dual exhaust system has a deeper, throatier sound to it. Some people prefer this. It even sounds loud and powerful when it is idle. Sometimes people associate a louder sound with better engine performance, but this is not necessarily the case. Sound performance doesn’t have any correlation to the mechanics of an exhaust system.
Cons of a Dual Exhaust System
Expense: A dual exhaust system is more expensive than a single exhaust system. This is because it requires additional parts, such as a second pipe.
Shorter Lifespan: Since the pipes in a dual exhaust system don’t get very warm, moisture is apt to condense in the exhaust and causes it to rust faster. This means you’ll be replacing the system sooner than you would a single exhaust.
Deeper Exhaust Sound: Although some car enthusiasts relish the deep, throaty sound that characterizes a dual exhaust system, you may prefer something quieter. Not everyone wants to draw attention when they are driving. If this is the case for you, a louder exhaust sound would be a disadvantage.
Keep in mind that it is not the quantity of pros and cons that you can identify, it’s their quality. Know what you want. Some pros and cons will have more or less meaning for you, depending on your personal preferences.
