What Factors Should You Consider When Choosing the Best Subaru Exhaust?

When choosing the best Subaru exhaust, several factors should be taken into account to ensure optimal performance and fitment.

• Material: The material of the exhaust system significantly impacts durability and performance. Stainless steel is the most popular choice due to its resistance to corrosion and high temperatures, while aluminized steel is more affordable but may not last as long in harsh conditions.
• Sound Level: Different exhaust systems produce varying sound levels, which can affect your driving experience. Consider whether you prefer a deep, aggressive tone for a sportier feel or a quieter system for a more subdued ride, as some systems are designed specifically for noise reduction.
• Fitment: Ensuring that the exhaust system fits your specific Subaru model is crucial for optimal performance. Look for exhaust systems that are specifically designed for your model year and trim to avoid complications during installation and to ensure proper alignment with the vehicle’s undercarriage.
• Performance Gains: Different exhaust systems offer different levels of performance enhancement, such as increased horsepower and torque. Research dyno results and user reviews to find an exhaust that provides the performance improvements you are seeking, while also considering how it will affect your vehicle’s overall driving dynamics.
• Brand Reputation: The reputation of the manufacturer can impact the quality and reliability of the exhaust system. Choosing a well-known brand with positive reviews and testimonials can provide peace of mind regarding the product’s performance and longevity.
• Installation Difficulty: Some exhaust systems can be complex to install, requiring professional help or significant mechanical skills. Consider whether you are comfortable with DIY installation or if you would prefer a system that is easy to install with minimal modifications required.
• Legal Regulations: Be aware of local noise regulations and emissions laws that may affect your choice of exhaust. Some aftermarket exhaust systems may not comply with noise limits or emissions standards, which could lead to fines or the need for additional modifications.

What Are the Different Types of Subaru Exhaust Systems Available?

The different types of Subaru exhaust systems available cater to various performance and aesthetic preferences.

• Cat-Back Exhaust System: This system replaces the exhaust components from the catalytic converter to the rear of the vehicle. It is designed to improve exhaust flow, resulting in enhanced performance and a more aggressive sound, making it a popular choice among enthusiasts.
• Axle-Back Exhaust System: This type of exhaust system replaces the components from the rear axle to the back of the car, including the muffler and tailpipe. It is often chosen for its relatively easy installation and ability to modify sound without significantly affecting performance.
• Turbo-Back Exhaust System: This comprehensive system replaces the entire exhaust from the turbocharger outlet to the rear of the vehicle, including the downpipe. It maximizes exhaust flow, making it ideal for those seeking significant performance upgrades in turbocharged Subaru models.

How Do You Properly Install a Subaru Exhaust System?

To properly install a Subaru exhaust system, follow these essential steps:

• Gather Necessary Tools: Ensure you have all required tools such as a socket set, wrenches, jack stands, and a torque wrench for a safe and efficient installation.
• Prepare the Vehicle: Safely lift the Subaru using jack stands and remove any underbody covers that may obstruct access to the exhaust components.
• Remove the Old Exhaust System: Carefully detach the old exhaust system, starting from the rear and working towards the front, ensuring to unbolt any hangers and clamps without damaging surrounding components.
• Install New Exhaust Components: Begin installing the new exhaust parts, starting with the headers or downpipe if applicable, and work your way back, ensuring each segment is securely fastened and aligned properly.
• Check for Leaks: Once installation is complete, start the engine and check for any exhaust leaks, making adjustments as necessary to ensure a tight fit and optimal performance.
• Final Inspection: After confirming there are no leaks, perform a final inspection to ensure all bolts and hangers are tightened correctly and the exhaust system is properly secured.

Gathering the necessary tools is crucial for a successful installation; this includes a socket set for removing bolts, wrenches for tightening, and jack stands for safely elevating the vehicle. Having a torque wrench on hand is also important to ensure that bolts are tightened to the manufacturer’s specifications, preventing future issues.

Preparing the vehicle involves lifting it securely and removing any underbody protection that might hinder access to the exhaust system. This step is vital as it allows you to work safely and ensures you have clear visibility and access to all relevant components.

When removing the old exhaust system, start from the rear and work towards the front. This method minimizes the risk of damaging other components and makes it easier to access the bolts and hangers. Be cautious during this step, as some bolts may be rusted or corroded, requiring patience and possibly penetrating oil.

Installing the new exhaust components should be done methodically, beginning with the headers or downpipe. Ensure that each section is properly aligned and that all bolts and hangers are used to secure the system in place. Following the manufacturer’s instructions is crucial for a smooth installation process.

After the installation, it is essential to check for leaks by starting the engine and listening for abnormal sounds or observing any escaping gas. This step allows you to identify and resolve any issues before taking the vehicle on the road.

Finally, conduct a thorough inspection of the entire exhaust system to confirm that all bolts are tightened and that the system is securely mounted. This final check helps ensure the longevity and performance of your new Subaru exhaust system.

What Common Myths Surround Subaru Exhaust Systems?

Several common myths surround Subaru exhaust systems that can mislead enthusiasts and potential buyers.
