So, you're looking to amp up the sound and performance of your Lexus IS 350 F Sport (2021) with a new exhaust system? Awesome! You've come to the right place. Let's dive into everything you need to know about upgrading your exhaust, from why you should do it, to what to look for, and some top recommendations.

Why Upgrade Your Lexus IS 350 F Sport Exhaust?

Upgrading your Lexus IS 350 F Sport exhaust system is a fantastic way to enhance your driving experience. The stock exhaust system, while functional, often leaves enthusiasts wanting more in terms of sound and performance. An aftermarket exhaust can significantly improve both, giving your ride a more aggressive tone and potentially boosting horsepower and torque. Here's a detailed breakdown of the key benefits:

Enhanced Sound: This is often the primary reason many owners choose to upgrade. A performance exhaust system can transform the sound of your IS 350 F Sport, giving it a deeper, more resonant tone that commands attention. Whether you prefer a subtle growl or an all-out roar, there's an exhaust system out there to match your taste. The sound improvement isn't just about being louder; it's about achieving a richer, more refined exhaust note that complements the sporty character of the car.

Improved Performance: While the gains might not be massive, a well-designed aftermarket exhaust system can improve your engine's breathing. By reducing backpressure, the engine can expel exhaust gases more efficiently, leading to a slight increase in horsepower and torque. The impact on performance can be particularly noticeable in the mid-range, offering improved throttle response and a more engaging driving experience. Keep in mind that the actual performance gains can vary depending on the specific exhaust system and any other modifications you've made to your car.

Weight Reduction: Many aftermarket exhaust systems are made from lighter materials like stainless steel or titanium. This can result in a noticeable weight reduction compared to the factory exhaust, which is typically made from heavier steel. Reducing weight can improve your car's handling, acceleration, and overall agility. While the weight savings from an exhaust system alone might not be dramatic, it contributes to the overall effort of making your car lighter and more responsive.

Aesthetic Appeal: Let's face it, a shiny new exhaust system looks great! Many aftermarket options come with polished tips and a more aggressive design that can enhance the visual appeal of your car. Whether you're going for a subtle upgrade or a bold statement, the right exhaust system can add a touch of personalization and style to your IS 350 F Sport. The visual upgrade can be especially appealing if you frequently show your car or simply take pride in its appearance.

Increased Resale Value: While it's not guaranteed, a well-chosen and properly installed aftermarket exhaust system can potentially increase the resale value of your car. Many buyers appreciate performance upgrades that enhance the driving experience and set the car apart from the crowd. However, it's essential to choose a reputable brand and ensure that the installation is done professionally to maximize the potential impact on resale value. Keep all the original parts so you can revert to stock if needed.

When selecting an aftermarket exhaust, make sure to consider things like the materials used, the design, and the reputation of the manufacturer. A high-quality exhaust system will not only enhance the sound and performance of your IS 350 F Sport but also stand the test of time, providing you with years of driving enjoyment.

Types of Exhaust Systems for Your IS 350 F Sport

Alright, let's talk about the different types of exhaust systems you can get for your Lexus IS 350 F Sport. Knowing the options helps you nail down exactly what you're looking for. Here's a breakdown:

Axle-Back Exhaust: This is usually the most budget-friendly option. It replaces the parts of the exhaust system from the rear axle to the exhaust tips. Axle-back systems are popular because they're relatively easy to install and can provide a noticeable improvement in sound. While they might not offer significant performance gains, they're a great way to get a more aggressive exhaust note without breaking the bank. They typically include a muffler and exhaust tips, allowing you to customize the look of your car as well. The installation process is straightforward, often requiring just basic hand tools, making it a popular choice for DIY enthusiasts.

Cat-Back Exhaust: A cat-back system replaces the exhaust components from the catalytic converters back to the exhaust tips. This includes the mid-pipe and muffler. Cat-back systems generally offer better performance gains compared to axle-back systems due to the larger diameter piping and less restrictive mufflers. They can also provide a more significant improvement in sound, giving your IS 350 F Sport a deeper and more aggressive tone. The installation is a bit more involved than an axle-back system, but it's still manageable for experienced DIYers. Cat-back systems are a good balance between performance, sound, and cost, making them a popular choice for many IS 350 F Sport owners.

Header-Back Exhaust (Full Exhaust System): For the serious enthusiast looking for maximum performance gains, a header-back exhaust system is the way to go. This replaces the entire exhaust system, including the exhaust manifold (headers), catalytic converters, mid-pipe, and muffler. A full exhaust system can significantly improve exhaust flow, resulting in substantial horsepower and torque gains. However, header-back systems are the most expensive option and often require professional installation due to the complexity of the job. Depending on your local regulations, removing or replacing the catalytic converters may not be street legal, so it's essential to check your local laws before making this upgrade. While the performance benefits are undeniable, a header-back system is a significant investment that requires careful consideration.

Muffler Delete: This involves removing the muffler altogether, resulting in a very loud and aggressive exhaust note. While it's the cheapest option, it's generally not recommended for street use due to the excessive noise levels. Muffler deletes can also create drone inside the cabin, which can be annoying on long drives. In many areas, muffler deletes are illegal due to noise regulations, so it's essential to check your local laws before considering this modification. While it might seem like a simple and cost-effective way to increase the sound of your exhaust, the drawbacks often outweigh the benefits.

When choosing an exhaust system, think about what matters most to you. Are you primarily after a better sound, or are you looking for noticeable performance gains? Also, consider your budget and how comfortable you are with installation. Knowing this will help you narrow down your options and find the perfect exhaust system for your Lexus IS 350 F Sport.

Installation Tips and Considerations

So, you've picked out your exhaust system – congrats! Now, let's talk about getting it installed. Here are some tips and things to keep in mind:

Professional Installation vs. DIY:

• DIY: If you're mechanically inclined and have some experience working on cars, you might be able to install an axle-back or cat-back exhaust system yourself. Make sure you have the right tools, including a jack, jack stands, sockets, wrenches, and a torque wrench. Follow the instructions carefully and take your time. However, if you're not comfortable working on cars or if you're installing a header-back system, it's best to leave it to the professionals.
• Professional Installation: A professional mechanic will have the experience and expertise to install your exhaust system correctly and efficiently. They'll also have access to specialized tools and equipment that you might not have. While professional installation will cost more, it can save you time and hassle in the long run. Plus, you'll have peace of mind knowing that the job was done right.

Things to Consider During Installation:

• Proper Fitment: Make sure the exhaust system fits your car properly. Check for any clearance issues or rubbing against other parts of the car. If you encounter any problems, consult the manufacturer or a professional mechanic.
• Sealing the Connections: Use new gaskets and sealant to ensure a tight seal between the exhaust components. This will prevent leaks and ensure optimal performance.
• Torque Specs: Use a torque wrench to tighten all the bolts and nuts to the proper torque specifications. This will prevent them from coming loose over time.
• Exhaust Hangers: Make sure the exhaust system is properly supported by the exhaust hangers. This will prevent it from sagging or rattling.
• Heat Shields: Ensure that all heat shields are properly installed to protect surrounding components from excessive heat.

Post-Installation Checks:

• Check for Leaks: After the installation is complete, start the car and listen for any exhaust leaks. If you hear any leaks, tighten the connections or replace the gaskets as needed.
• Check for Rattling: Drive the car around and listen for any rattling or vibrations. If you hear any noises, check the exhaust hangers and make sure the system is not rubbing against anything.
• Monitor Performance: Pay attention to how the car performs after the installation. You should notice a slight improvement in throttle response and acceleration. If you don't notice any difference, double-check the installation and make sure everything is working properly.
