A Subaru exhaust system is a great way to smooth out your ride. An aftermarket exhaust system can improve your vehicle’s performance and sound while reducing engine noise and improving fuel economy. It will also give your engine more power and torque, allowing you to get more out of your engine. An exhaust system can also help reduce emissions, making your car more environmentally friendly. With an aftermarket exhaust system, you can rest assured knowing that your ride will be smoother and better performing than ever.
Benefits of an Exhaust System
1. Improved Performance: An exhaust system helps to increase engine performance by allowing the exhaust gases to be expelled from the engine more efficiently. This allows for more air to enter the engine and exit through the exhaust system which helps to increase power and torque.
2. Improved Fuel Economy: An exhaust system can also help to improve fuel economy by reducing back pressure in the exhaust system. This helps to reduce the amount of fuel used by the engine which can help to lower running costs.
3. Reduced Emissions: An exhaust system helps to reduce harmful emissions from the vehicle by allowing the exhaust gases to be expelled from the engine more efficiently. This helps to reduce the amount of pollutants released into the atmosphere.
4. Improved Sound: An exhaust system can also help to improve the sound of the vehicle by reducing back pressure in the exhaust system. This helps to reduce the amount of noise emitted from the vehicle which can be pleasing to the ear.
Common Types of Exhaust Systems
1. Cat-Back Exhaust System: This is the most common type of aftermarket exhaust system, and is designed to increase horsepower and performance. It replaces the existing pipes and mufflers from the catalytic converter back, usually with larger-diameter pipes and high-flow mufflers.
2. Shorty Headers: Shorty headers are a type of exhaust manifold that is shorter and more efficient than the factory manifold. They are designed to reduce backpressure and increase exhaust flow, allowing the engine to breathe easier and make more power.
3. Axle-Back Exhaust System: This type of exhaust system replaces the pipes and mufflers from the rear axle of the vehicle back, usually with larger-diameter pipes and high-flow mufflers. It is designed to increase horsepower and performance but isn’t as comprehensive as a cat-back system.
4. Turbo-Back Exhaust System: A turbo-back exhaust system is designed for vehicles with turbochargers and is designed to increase performance and reduce turbo lag. It replaces all the pipes and mufflers from the turbocharger back, usually with larger-diameter pipes and high-flow mufflers.
5. Custom Exhaust System: Custom exhaust systems are designed and built to the exact specifications of the vehicle and can include various types of pipes, mufflers, and other components. They are designed to optimize performance and sound and are usually more expensive than pre-made systems.
How to Maintain Your Exhaust System
1. Monitor Your Exhaust System: Make sure you keep an eye on your exhaust system for any signs of visible wear or damage. Pay attention to noises such as rattling, popping, or hissing.
2. Replace Worn Parts: If you notice any signs of wear or damage, replace the parts as soon as possible. The longer you wait, the more costly the repair could be.
3. Check for Leaks: Regularly inspect for any leaks in the system. If you find any, have them repaired right away.
4. Clean the Exhaust System: Cleaning the exhaust system can help to reduce the buildup of dirt and debris, which can cause clogs and blockages. Use a brush or vacuum to remove any buildup.
5. Inspect the Pipes: Inspect the pipes of your exhaust system for any signs of rust or corrosion. If you find any, have them repaired or replaced.
6. Use the Right Fuel: Make sure you are using the right fuel for your vehicle. If you are using the incorrect type of fuel, it can cause damage to the exhaust system.
7. Keep it Properly Tuned: Make sure your vehicle is properly tuned. This will help ensure that the exhaust system is running efficiently and effectively.
How to Upgrade Your Exhaust System
1. Choose the Right Exhaust System. First, you must decide what type of exhaust system you want. Consider the type of vehicle you have, the sound you want, and the budget you have.
2. Buy the Right Parts. Once you’ve decided on an exhaust system, you need to buy the right parts. You’ll need a muffler, exhaust pipes, catalytic converter, and other related components.
3. Install the New Parts. To install the new parts, you’ll need to remove the existing exhaust system. This may require cutting, drilling, and welding. If you don’t feel comfortable doing this on your own, it’s best to hire a professional.
4. Enjoy the Sound. After the exhaust system is installed, you can enjoy the sound of your upgraded exhaust system. Be sure to take it for a test drive to make sure everything is working properly.
Troubleshooting Common Exhaust System Problems
1. Exhaust Leak: Exhaust leaks can be caused by a variety of issues, such as a loose clamp, a damaged gasket, a cracked exhaust manifold, or a hole in the exhaust system. To check for an exhaust leak, start the engine and listen for any unusual sounds. If you hear a whistling sound coming from the engine bay, then you likely have an exhaust leak. To fix the leak, you’ll need to identify the source of the leak and replace the faulty part.
2. Muffler or Exhaust Pipe Rust: Rust is a common problem with exhaust systems, especially in older vehicles. To inspect for rust, look for any discoloration or flaking on the pipes or muffler. If you notice any signs of rust, you’ll need to replace the affected parts.
3. Exhaust System Too Loud: An overly loud exhaust system is usually caused by an exhaust leak or an aftermarket part that isn’t properly installed. To fix the issue, check for any exhaust leaks and make sure all aftermarket parts are installed correctly. If the issue persists, you may need to replace the muffler or exhaust pipe.
4. Smell of Gas: If you smell gas while driving, this is usually caused by a faulty exhaust system. This issue can be dangerous, as it can lead to carbon monoxide poisoning. If you smell gas, you’ll need to inspect your exhaust system for any leaks or faulty parts. If necessary, you may need to replace the exhaust system.
Exhaust systems are an important component of a vehicle’s performance, allowing for a safe and efficient way to reduce pollutants and noise. They help to protect the environment, improve engine performance, and reduce the risk of health issues associated with exposure to exhaust gases. The right exhaust system can also provide the driver with a more comfortable and enjoyable driving experience. With advancements in exhaust systems, the performance of vehicles has improved significantly, leading to cleaner air, increased fuel efficiency, and improved sound quality. Ultimately, exhaust systems play an important role in keeping cars running safely and efficiently.
