Unlock the Beast: How to Make Subaru Legacy Louder Than Ever Before

The Subaru Legacy is known for its reliability, practicality, and all-wheel drive prowess. But let’s be honest, its stock exhaust isn‘t exactly a symphony of power. If you’re looking to add a little more character and a touch of aggression to your Legacy’s soundtrack, you’ve come to the right place. This guide will explore various methods on how to make Subaru Legacy louder, from subtle tweaks to full-blown exhaust upgrades.

Understanding the Basics: Exhaust Systems and Sound

Before we dive into the specifics, let’s understand the basics of exhaust systems and how they contribute to a car’s sound.

An exhaust system is essentially a series of pipes that carry exhaust gases from the engine to the atmosphere. The components include:

• Manifold: This is where exhaust gases first exit the engine.
• Catalytic Converter: This component reduces harmful emissions.
• Intermediate Pipe: Connects the manifold to the muffler.
• Muffler: This is the primary sound-dampening component.
• Tailpipe: The final pipe that releases exhaust gases into the atmosphere.

The size, shape, and material of these components, particularly the muffler, heavily influence the exhaust note.

Method 1: Muffler Delete or Replacement

One of the most common and straightforward ways to make your Subaru Legacy louder is to modify or replace the muffler.

Muffler Delete:

This involves removing the stock muffler entirely. This is the most aggressive option, resulting in a significantly louder, more raspy exhaust note. However, it can also be quite loud and may not be street-legal in some areas.

Muffler Replacement:

A more controlled approach is to replace the stock muffler with an aftermarket performance muffler. These mufflers are designed to enhance the sound while still maintaining a reasonable volume level. Many aftermarket mufflers offer different sound levels and tones, allowing you to choose the perfect balance for your preferences.

Method 2: Cat-Back Exhaust System

For a more comprehensive and impactful exhaust upgrade, consider installing a cat-back exhaust system. This system replaces the entire exhaust system from the catalytic converter back, including the intermediate pipe, muffler, and tailpipe.

Cat-back systems offer several advantages:

• Increased Horsepower and Torque: These systems are often designed to improve airflow and reduce backpressure, potentially leading to small gains in horsepower and torque.
• Enhanced Sound: Cat-back systems offer a more refined and consistent sound compared to simply replacing the muffler.
• Improved Aesthetics: Many cat-back systems come with stylish tailpipes that can enhance the visual appeal of your Legacy.

Method 3: Resonator Delete

The resonator is a smaller component within the exhaust system that helps to dampen sound. Removing or replacing the resonator can create a deeper, more aggressive sound. This method is generally less invasive than a full muffler replacement and can offer a noticeable difference in sound without being overly loud.

Method 4: Cold Air Intake

While not directly related to the exhaust system, a cold air intake can indirectly affect the sound of your Subaru Legacy. This modification replaces the stock air intake with a system that draws cooler, denser air into the engine. This can result in a more throaty intake sound, especially during acceleration.

Method 5: Electronic Sound Enhancers

For those who want a louder exhaust sound without modifying the actual exhaust system, electronic sound enhancers are an option. These devices use speakers and electronic controls to create a simulated exhaust sound that can be adjusted to different levels and tones.

Choosing the Right Approach: Factors to Consider

When deciding how to make your Subaru Legacy louder, several factors should be considered:

• Budget: Muffler replacement is generally the most affordable option, while cat-back systems and electronic sound enhancers can be more expensive.
• Sound Preferences: Consider the desired sound level and tone. Do you want a subtle growl or a full-blown roar?
• Legality: Check local laws and regulations regarding exhaust modifications. Some areas have strict noise ordinances.
• Performance Impact: While exhaust modifications can enhance sound, they may not necessarily lead to significant performance gains.
• Maintenance: Aftermarket exhaust systems may require regular maintenance, such as cleaning or replacing components.

Tips for a Successful Installation

If you’re planning on installing an aftermarket exhaust system yourself, here are some tips:

• Choose reputable brands: Look for high-quality exhaust systems from reputable manufacturers.
• Read installation instructions carefully: Familiarize yourself with the installation process before starting.
• Use proper tools: Ensure you have the necessary tools and equipment for the job.
• Double-check connections: Make sure all connections are secure and tight.
• Test for leaks: After installation, check for any exhaust leaks.

Beyond the Sound: Other Considerations

While making your Subaru Legacy louder can be a fun and rewarding experience, it’s important to remember that exhaust modifications can impact other aspects of your car:

• Fuel economy: A louder exhaust can potentially reduce fuel efficiency, especially if it’s significantly louder than the stock system.
• Interior noise: A louder exhaust will also increase interior noise levels, which may be undesirable for some drivers.
• Emissions: While aftermarket exhaust systems are generally designed to meet emissions standards, it’s essential to ensure that your car still passes emissions testing.

The End of the Road: A More Powerful Subaru Legacy

Making your Subaru Legacy louder can be a great way to personalize your car and express your driving style. Whether you opt for a simple muffler replacement or a full cat-back system, there are various options to achieve the desired sound. Remember to consider your budget, sound preferences, and legal requirements before making any modifications. By following these guidelines, you can unleash the roar of your Subaru Legacy and enjoy a more powerful and engaging driving experience.

Popular Questions

1. Can I make my Subaru Legacy louder without modifying the exhaust system?

While modifying the exhaust system is the most effective way to make your car louder, you can achieve subtle sound enhancements without altering the exhaust. For example, installing a cold air intake can create a more throaty intake sound. Additionally, electronic sound enhancers can simulate a louder exhaust note.

2. How loud is too loud for a Subaru Legacy exhaust?

The acceptable noise level for a Subaru Legacy exhaust varies depending on local regulations and personal preferences. Generally, it’s best to avoid excessively loud exhaust modifications that could cause noise pollution or annoy other drivers. Aim for a sound that enhances the car’s character without being overly intrusive.

3. What are the potential downsides of making my Subaru Legacy louder?

While a louder exhaust can be appealing, it can also have some downsides. It can negatively impact fuel economy, increase interior noise, and potentially violate local noise ordinances. Additionally, some aftermarket exhaust systems may require more frequent maintenance.

4. Can I install an aftermarket exhaust system myself?

Installing an aftermarket exhaust system can be a challenging task, requiring some mechanical knowledge and experience. If you’re not comfortable with DIY projects, it’s recommended to have a professional mechanic install the system to ensure proper fitment and prevent potential issues.
