Why Upgrade Your 2017 Lexus IS350 Exhaust?

Okay, so why bother replacing the perfectly good exhaust that came from the factory? Well, there are several compelling reasons. The stock exhaust on the 2017 IS350, while adequate, is designed with a focus on noise reduction and fuel efficiency. This means it often sacrifices a bit of the engine's potential performance and, let's be honest, the auditory experience. Upgrading to an Invidia exhaust can address these issues and provide some sweet rewards! First off, an aftermarket exhaust is all about performance enhancements. Invidia exhausts are engineered to improve exhaust flow, which, in turn, helps the engine breathe more freely. This means improved horsepower and torque, and better acceleration. You'll likely feel a noticeable difference, especially in the mid-range. Secondly, the sound. This is where things get really fun. Invidia exhausts are famous for their aggressive, yet refined, sound. They give the IS350 a deeper, more resonant tone that lets everyone know you mean business. Forget the subtle hum; your IS350 will now announce its presence with authority. Thirdly, there's the aesthetic appeal. An Invidia exhaust often features a more stylish design, with high-quality materials and attractive tips. This can significantly enhance the look of your car, especially if you opt for a system with polished stainless steel or titanium tips. And finally, the potential for weight reduction. Many aftermarket exhausts, including Invidia's, are lighter than the factory system. This further contributes to improved performance and handling. Therefore, the 2017 Lexus IS350 will experience a great improvement with the Invidia exhaust.

The Benefits in a Nutshell

• Increased Horsepower and Torque: Improved exhaust flow translates to more power.
• Enhanced Sound: A deeper, more aggressive exhaust note.
• Improved Aesthetics: Stylish design and premium materials.
• Weight Reduction: Potentially lighter than the stock system.
• Better Throttle Response: A more responsive feel to the accelerator.

Choosing the Right Invidia Exhaust for Your 2017 Lexus IS350

Alright, so you're sold on the idea of an Invidia exhaust. Awesome! Now comes the fun part: choosing the right one. Invidia offers a range of exhaust systems for the 2017 IS350, and each has its own unique features and characteristics. Understanding the different options available is crucial to ensure you get a system that meets your specific needs and preferences. Typically, you'll be choosing between a cat-back exhaust system or an axle-back exhaust system. Also, the material is very important when picking an Invidia exhaust. Let's break down some of the most popular Invidia exhaust options and the factors you should consider when making your decision.

Cat-Back vs. Axle-Back Systems

• Cat-Back Exhaust Systems: Cat-back systems replace the exhaust system from the catalytic converters (the “cats”) back. This typically includes the mid-pipe, muffler, and exhaust tips. Cat-back systems generally offer greater performance gains and a more significant change in sound compared to axle-back systems. They also tend to be a bit more expensive due to the increased complexity and amount of components involved. If you're serious about performance and want the most aggressive sound, a cat-back system is the way to go.
• Axle-Back Exhaust Systems: Axle-back systems replace the exhaust system from the rear axle back. This typically includes the muffler and exhaust tips. Axle-back systems are generally more affordable and easier to install than cat-back systems. They still offer a noticeable improvement in sound and can provide some performance gains, but the impact is usually less significant than with a cat-back system. If you're on a budget or looking for a more subtle upgrade, an axle-back system could be a good choice.

Material Matters

• Stainless Steel: Stainless steel is a popular choice for exhaust systems due to its durability and resistance to corrosion. It's a great balance of cost and performance, making it a solid option for daily drivers and enthusiasts alike. Invidia offers several stainless steel exhaust options for the IS350.
• Titanium: Titanium is a premium material known for its incredibly light weight and high strength. Titanium exhausts offer the ultimate in performance and weight savings. They also have a unique sound and a distinctive appearance. However, titanium exhausts are typically the most expensive option.

Other Factors to Consider

• Sound Level: How loud do you want your exhaust to be? Invidia systems range from moderately aggressive to very aggressive. Read reviews and watch videos to get an idea of the sound level before making your purchase.
• Exhaust Tips: Invidia offers a variety of exhaust tip styles. Choose tips that complement the look of your car. If you have any additional modifications, such as an aftermarket intake, you must also be sure that the exhaust system fits your vehicle. Be sure to check the manufacturer's website or contact a reputable retailer to ensure compatibility.

Step-by-Step: Installing Your Invidia Exhaust on Your 2017 Lexus IS350

Alright, you've got your shiny new Invidia exhaust and you're ready to get it installed. Awesome! While it's always a good idea to have a professional install the exhaust if you're not comfortable, this is a job that can be tackled in your garage with the right tools and some patience. Here's a general overview of the installation process. Before you start, make sure you have all the necessary tools and equipment. This typically includes a set of jack stands, a wrench set, a socket set, penetrating oil (like WD-40), and a torque wrench. It's also a good idea to have some gloves and safety glasses.

Preparation is Key

1. Safety First: Always work in a well-ventilated area and wear appropriate safety gear, including eye protection and gloves. Never work under a car supported only by a jack. Use jack stands to securely support the vehicle. Safety first, guys!
2. Raise and Secure the Vehicle: Safely raise your Lexus IS350 and secure it on jack stands. Make sure the vehicle is stable and won't move during the installation. It's best to perform the work on a level surface.
3. Soak the Hardware: Spray all the exhaust bolts and connections with penetrating oil. This helps loosen any rust or corrosion and makes removing the old exhaust easier.

Removing the Factory Exhaust

1. Disconnect the Sensors (if applicable): Some exhaust systems may have sensors connected to them. Carefully disconnect any sensors. Be gentle, and take note of where they connect for reinstallation.
2. Unbolt the Exhaust: Carefully unbolt the exhaust system from the catalytic converters (for cat-back systems) or the rear axle (for axle-back systems). Use a wrench or socket set to remove the bolts. If the bolts are stubborn, apply more penetrating oil and let it soak for a while. You may need to use a breaker bar to break them loose.
3. Remove the Exhaust: Once all the bolts are removed, carefully lower the factory exhaust system. You may need to wiggle it a bit to get it free. Be careful not to damage any other components.

Installing the Invidia Exhaust

1. Install the New Components: Align the new Invidia exhaust components with the existing connections. Start by loosely attaching all the components. Do not fully tighten anything at this stage.
2. Align and Adjust: Make sure all the components are aligned correctly. You may need to adjust the position of the exhaust hangers to get the system to fit properly.
3. Tighten the Bolts: Once everything is aligned, tighten all the bolts to the manufacturer's specified torque. Use a torque wrench to ensure proper tightness.
4. Reconnect the Sensors (if applicable): If you disconnected any sensors, reconnect them now. Double-check all connections.
5. Final Checks: Before lowering the vehicle, double-check all connections and make sure everything is secure. Also, ensure the exhaust tips are aligned properly.

Finishing Up

1. Lower the Vehicle: Carefully lower the vehicle to the ground.
2. Start the Engine and Check for Leaks: Start the engine and let it run for a few minutes. Check for any exhaust leaks. You should be able to hear any leaks.
3. Enjoy the Sound: Now, take your IS350 for a spin and enjoy the new, aggressive sound of your Invidia exhaust! You did it!

Maintaining Your Invidia Exhaust

Once your Invidia exhaust is installed, proper maintenance is key to keeping it in top condition and ensuring it provides years of performance and enjoyment. Regular maintenance not only helps preserve the exhaust system's appearance but also ensures it continues to function optimally. While Invidia exhausts are built to last, they do require some care. Here's how to keep your new exhaust looking and sounding its best. Keep in mind that a well-maintained exhaust system not only enhances the aesthetics of your vehicle but also contributes to its overall longevity and resale value.

Cleaning and Inspection

• Regular Cleaning: Regularly clean your exhaust system to remove any dirt, grime, or road salt. This is especially important if you live in an area with harsh weather conditions or salted roads. Use a mild soap and water solution and a soft cloth or sponge to clean the exhaust. Avoid using abrasive cleaners or steel wool, as these can scratch the surface.
• Inspect Regularly: Regularly inspect your exhaust system for any signs of damage, such as dents, leaks, or corrosion. Check the welds, flanges, and hangers for any cracks or damage. Address any issues promptly to prevent them from worsening. Regular inspections can help catch potential problems early, preventing more serious and costly repairs down the road. It's a great practice to include this inspection during your routine vehicle maintenance.

Preventing Corrosion

• Protect from Salt: If you live in an area where roads are salted during the winter, consider washing your car frequently to remove salt buildup. Salt can accelerate corrosion, so removing it regularly is crucial. Consider applying a protectant spray designed for exhaust systems to create a barrier against the elements.
• Keep it Dry: Try to keep your exhaust system as dry as possible. After washing your car, allow the exhaust system to dry completely. Driving your car after a wash can help dry the exhaust system quickly. Avoid parking your car in areas prone to excessive moisture, such as near sprinklers.

Other Maintenance Tips

• Check the Hangers: Inspect the exhaust hangers periodically to ensure they are in good condition and holding the exhaust system securely. Replace any damaged or worn hangers. Worn hangers can lead to excessive vibration and potential damage to the exhaust system.
• Listen for Changes: Pay attention to any changes in the exhaust sound. Any unusual noises, such as rattles or leaks, could indicate a problem that needs attention. Addressing these issues promptly can prevent more serious damage and maintain the exhaust system's performance.
• Professional Inspection: Consider having your exhaust system inspected by a professional mechanic at least once a year. A professional inspection can help identify any potential problems that you may have missed. A qualified mechanic can provide expert advice and recommend any necessary maintenance or repairs.
