Many vehicles have 2 exhaust systems to help them run more efficiently. The dual exhaust system cuts the back pressure and allows the engine to expel air more easily. The two pipes can also give the vehicle a sportier look and a more aggressive sound. Here are the common types of 2 exhaust systems that buyers can find in the market:
Split Exhaust System
The split exhaust system takes one pipe from the exhaust manifold and splits it into two pipes down the line. This setup allows for more airflow and emits a louder sound. The split exhaust system is popular among performance cars and aftermarket applications. It is also known as the ""cutout"" because it essentially cuts the main exhaust pipe and adds a second pipe.
Rear-Dual Exhaust System
In the rear-dual exhaust system, a single pipe comes out of the exhaust manifold and transforms into two pipes that run to the rear of the vehicle. This setup is great for trucks and SUVs since it enhances low-end torque. The rear-dual exhaust system is common in heavy-duty vehicles.
Dual-Dump Exhaust System
The dual-dump exhaust system uses two pipes that exit the vehicle right after the muffler. The pipes point toward the ground and do not extend past the vehicle's body. This exhaust system is ideal for racing applications where the vehicle is not driven on public roads. Because the exhaust exits the vehicle so quickly, it can be very loud.
True Dual Exhaust System
The true dual exhaust system uses two pipes from the engine to the tailpipe. The system improves high-end power and gives the vehicle a throaty sound. The true dual exhaust is suitable for high-performance vehicles and applications where power is a priority.
Turbo-Dual Exhaust System
The turbo-dual exhaust system combines the benefits of the true dual and rear-dual systems. It improves low-end torque and high-end power, making it a good choice for performance cars. This system is popular in aftermarket applications.
The specifications of 2 exhausts vary depending on the type and the needs of the vehicle.
Material:
2 exhaust pipes are mainly made with durable materials. Stainless steel is a popular choice because it is resistant to corrosion and can withstand high temperatures. Titanium is also used because it is lighter and more heat resistant than steel.
Diameter:
2 exhaust pipes come in different sizes. The diameter of the pipe affects the sound and performance of the vehicle. Larger pipes allow for more airflow, which can improve performance. They also create a deeper sound. Smaller pipes produce a higher pitch sound and may slightly restrict airflow.
Length:
The length of a dual exhaust pipe can affect its placement on the vehicle. Longer pipes may extend further out the back, changing the appearance and sound of the exhaust. Shorter pipes take up less space but may not be as effective at dissipating engine fumes.
Muffler Type:
The muffler on a 2 pipe exhaust plays a key role in noise control. Different types of mufflers produce varying sounds. For example, chambered mufflers create a rumbling noise while straight-through mufflers allow sound to pass straight through, resulting in a louder tone.
Tip Shape:
Exhaust tips come in different shapes and sizes. Common options include round, oval, square or rolled edges. The shape of the exhaust tip can influence the appearance and airflow of the exhaust system.
It is important to maintain 2 exhaust systems to avoid emissions problems and costly repairs. Here is how to maintain a 2 exhaust system:
Regular Inspection:
Check the exhaust system during every oil change. Look for signs of wear, damage or rust. Inspect all parts, including pipes, hangers, mufflers and catalytic converters. Early detection of problems helps avoid more serious issues down the road.
Keep it Clean:
Wash the outside of the exhaust system to remove dirt and debris. A build-up of materials can cause corrosion over time. Gently clean inside the exhaust tips too. A dirty appearance detracts from the look of the vehicle.
Replace Worn Parts:
Swap out any broken or rusted components with new ones. Using quality replacement parts helps maintain proper function and durability. For example, replace hangers that hold the exhaust pipes in place if they become frayed or brittle. Loose pipes create noise and may drag on the ground.
Address Performance Issues:
If the vehicle begins to sound different or has a decrease in power, check the exhaust system. Problems like a clogged catalytic converter restrict airflow and need prompt attention. Taking care of issues helps avoid damage to other engine parts.
Avoid Overloading:
Do not carry more weight in the vehicle than recommended. An overloaded exhaust system places stress on components like pipes and may lead to early failure. Follow manufacturer guidelines for optimal performance and longevity of the exhaust.
Choosing a dual exhaust system for a vehicle can be a complex process, but it can be simplified by following these steps:
Determine the goals
Establish what is desired from the dual exhaust system. Is it improved performance, a more aggressive sound, or simply an aesthetic upgrade?
Research the vehicle
Find out if the car is compatible with dual exhaust systems. Some vehicles are designed to work optimally with single exhaust systems.
Consult with an expert
An expert can offer valuable advice on the benefits and drawbacks of each exhaust system. They can also provide recommendations based on the specific vehicle.
Consider performance vs. sound
Performance: Torque and horsepower are often increased with dual exhaust systems. Sound: Dual exhaust systems typically produce a louder, more aggressive sound.
Research the parts
Understand what headers, catalytic converters, and mufflers are. Headers replace the factory exhaust manifold and can improve engine breathing. Catalytic converters reduce harmful emissions. Mufflers control the sound of the exhaust.
Quality matters
Invest in quality parts for better performance and longevity. Cheap parts can fail quickly and might not perform well.
Consider professional installation
While some may attempt to install the dual exhaust system themselves, it can be complicated. Professional installation ensures proper fitment and performance.
Budget
Exhaust systems come in various price ranges. Set a budget but remember that quality and performance are essential.
Brand reputation
Choose well-known brands with positive reviews. This ensures that the parts will fit well and last a long time.
Below are some tips on how to DIY and replace 2-exhaust:
Identify the problem:
Finding out what is wrong with the dual exhaust system should be the first step in any repair. This entails listening for strange noises, inspecting the system for leaks or damage, and seeing if there are any warning lights or messages on the dashboard that point to an exhaust issue.
Gather the necessary tools and materials:
Once the issue has been identified, gathering the necessary tools and materials to fix it is crucial. Wrenches, pliers, a jack and jack stands, and replacement parts like mufflers or pipes may be included in this. It is also a good idea to have exhaust repair tape or putty on hand for minor leaks or damage.
Prepare the vehicle:
Preparing the vehicle involves making sure it is safe and ready to work on. This includes parking on a flat surface, engaging the parking brake, and ensuring the vehicle is powered down. Additionally, it is essential to allow the exhaust system to cool before working on it, as it can become heated during operation.
Perform the repair:
Depending on the issue, different repairs may be required. Replacing the muffler or pipe may be necessary if there is damage. Use exhaust repair tape or putty to seal minor leaks or cracks.
