An upgraded exhaust not only improves the sound of your vehicle but can also boost its performance. In this article, we'll delve into the various exhaust options available for the 2016 Lexus IS350, helping you make an informed decision. We'll cover everything from axle-back and cat-back systems to full exhaust replacements, discussing the pros, cons, and considerations for each. Understanding these options will ensure you select an exhaust system that aligns with your preferences and driving needs.

Understanding Exhaust Systems

Before diving into specific recommendations, let's clarify the different types of exhaust systems you might encounter. The exhaust system is crucial for channeling exhaust gases away from the engine, reducing emissions, and influencing the vehicle's sound and performance. Knowing the components and types of systems will help you navigate the market more effectively.

Key Components of an Exhaust System

• Exhaust Manifold: This is the first part of the exhaust system, collecting exhaust gases from the engine cylinders.
• Catalytic Converter: Designed to reduce harmful emissions by converting pollutants into less harmful substances.
• Resonator: Helps to control and reduce specific frequencies to refine the exhaust sound.
• Muffler: The primary sound-dampening component, significantly reducing the overall noise level.
• Pipes: Connect all the components, allowing for the flow of exhaust gases.

Types of Exhaust Systems

• Axle-Back Systems: These systems replace everything from the rear axle back, typically including the muffler and exhaust tips. They are relatively easy to install and primarily affect the exhaust sound.
• Cat-Back Systems: These systems replace the exhaust components from the catalytic converter back, offering a more comprehensive upgrade that can improve both sound and performance.
• Full Exhaust Systems (Headers-Back): These are the most comprehensive option, replacing the entire exhaust system from the exhaust manifold (headers) to the tailpipes. This can lead to significant gains in both power and sound, but they are also the most expensive and complex to install.

Factors to Consider When Choosing an Exhaust System

Selecting the right exhaust system involves more than just picking one that sounds good. Several factors should influence your decision, including your budget, desired sound level, performance goals, and local regulations. Considering these aspects will help you make a choice that you'll be happy with in the long run.

Sound Level and Tone

The sound of your exhaust is a subjective matter, but it's important to consider how it will affect your daily driving experience. Some people prefer a loud, aggressive exhaust note, while others prefer something more subtle and refined. It's a great idea to listen to sound clips of different exhaust systems on a 2016 Lexus IS350 before making a decision. Also, consider the potential for drone, which is a low-frequency hum that can be annoying during highway driving. Reading reviews and watching videos can help you gauge the sound level and tone of different exhaust systems. It’s also crucial to think about how the sound will affect your neighbors and passengers. A very loud exhaust might be fun for a short drive, but it could become tiresome on longer trips.

Performance Gains

While most exhaust upgrades primarily focus on sound, some systems can also improve your vehicle's performance. Look for systems that are designed to optimize exhaust flow, as this can lead to increased horsepower and torque. Cat-back and full exhaust systems are more likely to provide noticeable performance gains compared to axle-back systems. However, don't expect dramatic improvements unless you're also making other performance modifications. Many manufacturers provide dyno charts or performance data to illustrate the potential gains from their exhaust systems. Keep in mind that real-world results can vary depending on your vehicle's specific configuration and driving conditions. Performance gains are often more noticeable at higher RPMs, so consider how you typically drive when evaluating potential upgrades.

Installation

The ease of installation is another important factor to consider, especially if you plan to install the exhaust system yourself. Axle-back systems are generally the easiest to install, often requiring only basic tools and mechanical knowledge. Cat-back systems are more involved, but still manageable for experienced DIYers. Full exhaust systems can be quite complex, often requiring professional installation. Check the manufacturer's instructions and read reviews to get an idea of the installation process. Some exhaust systems may require modifications to your vehicle, such as cutting or welding, which can add to the cost and complexity. If you're not comfortable with the installation process, it's best to have a professional mechanic handle the job. This will ensure that the exhaust system is installed correctly and safely.

Budget

Exhaust systems can range in price from a few hundred dollars to several thousand, so it's important to set a budget before you start shopping. Axle-back systems are generally the most affordable, followed by cat-back systems, and then full exhaust systems. Keep in mind that the price of the exhaust system is not the only cost to consider. You may also need to factor in the cost of installation, as well as any additional parts or modifications that may be required. It's always a good idea to get quotes from multiple vendors and installers to ensure you're getting the best possible price. Don't sacrifice quality for price, as a cheaper exhaust system may not last as long or perform as well as a more expensive one. Consider the long-term value of the exhaust system, including its durability, performance, and overall satisfaction.

Local Regulations

Before upgrading your exhaust system, it's important to be aware of any local regulations regarding exhaust noise and emissions. Some states and municipalities have strict laws about exhaust modifications, and you could face fines or be required to remove the aftermarket system if it doesn't comply. Check with your local authorities or consult with a qualified mechanic to ensure that your chosen exhaust system is legal in your area. Some exhaust systems are specifically designed to meet emissions standards, while others are intended for off-road use only. Be sure to choose a system that is appropriate for your vehicle and your intended use. Ignoring local regulations can lead to costly fines and headaches, so it's always best to be informed before making any modifications.

Conclusion

Upgrading the exhaust system on your 2016 Lexus IS350 can be a rewarding experience, enhancing both the sound and performance of your vehicle. By understanding the different types of exhaust systems available and considering factors such as sound level, performance gains, installation, budget, and local regulations, you can make an informed decision that aligns with your preferences and needs.
