All vehicles are equipped with an exhaust system, which is responsible for transporting burned engine exhaust gases from a vehicle’s engine exhaust port and directing them out of the vehicle’s tail pipe. Exhaust systems come in both single and dual varieties.
Benefits of Dual Exhaust
1. Increases Efficiency and Horsepower
Setting up a dual exhaust on a vehicle can help increase engine efficiency and horsepower. This will increase the amount of towing force a vehicle can bring to bear. It can also decrease the lag time many vehicles experience in getting to high speeds on the road. With the dual exhaust quickly funneling burnt gases away from the engine, more oxygen can be brought in, allowing the engine to reach peak performance in seconds.
2. Enhanced Sound Options
Besides the obvious gain in horsepower and engine efficiency, a vehicle with a dual exhaust typically features that low, booming sound that is normally relegated to muscle cars. This can instantly turn the vehicle into a head-turner when traveling down the road. Some local authorities have noise ordinances that drivers must be wary of, but with the customization options available, including the type of muffler chosen, drivers are sure the find the perfect balance between legality and coolness.
3. Increases Fuel Economy
Setting up a dual exhaust will also reduce strain on the engine, because the engine won’t have to work as hard to push gases out and bring fresh air in. This also increases the fuel economy of an engine by allowing it to make better use of power and produce more energy overall.
4. Saves the Engine
Setting up a dual exhaust system can help keep the engine cool as well. The constant flow of fresh air over the engine from outside helps keep the temperature down while the dual exhaust pulls hot gases away from the engine that much faster. It has also been found that the engines in dual exhaust cars last longer, which means car owners can stay on the road for many more years.
Single Exhaust Benefits
1. Cheap
One of the biggest is that it’s the cheapest: most vehicles are factory equipped as single exhaust, meaning you don’t have to change anything.
2. Light
Single exhaust systems are also lighter and increase your exhaust gas velocity.
3. Easier to modify or replace
They are also easier to replace and cheaper to modify. However, your absolute flow suffers, as its limited to a single pipe.
