So, you're thinking about upgrading the exhaust on your 2021 Lexus RC 350 F Sport, huh? Awesome choice! The RC 350 F Sport is already a sweet ride, but a new exhaust system can really take it to the next level. We're talking enhanced sound, improved performance, and a more aggressive look. Let's dive into everything you need to know about choosing the right exhaust for your RC 350 F Sport.

Why Upgrade Your Lexus RC 350 F Sport Exhaust?

Before we get into specific exhaust options, let's talk about why you might want to upgrade in the first place. There are several compelling reasons:

• Enhanced Sound: This is the big one for most people. The stock exhaust on the RC 350 F Sport is pretty tame. An aftermarket exhaust can give you a deeper, more aggressive exhaust note that will turn heads wherever you go. Imagine cruising down the street with a throaty growl emanating from your Lexus – that's the power of a good exhaust system.
• Improved Performance: While the gains might not be massive, a less restrictive exhaust system can improve your engine's breathing, leading to slight increases in horsepower and torque. This is because the engine doesn't have to work as hard to expel exhaust gases, which frees up some extra power. It's like letting your engine breathe a sigh of relief!
• Aggressive Aesthetics: Many aftermarket exhausts come with stylish tips that can enhance the look of your RC 350 F Sport. Whether you prefer a classic chrome finish or a more modern blacked-out look, there's an exhaust tip out there to match your personal style. It's a subtle but effective way to make your car stand out from the crowd.
• Weight Reduction: Some aftermarket exhaust systems are made from lighter materials like stainless steel or titanium, which can reduce the overall weight of your car. This can improve handling and acceleration, making your RC 350 F Sport even more fun to drive. Every little bit counts when it comes to performance!

Types of Exhaust Systems for Your RC 350 F Sport

Now that you know why you might want to upgrade your exhaust, let's take a look at the different types of exhaust systems available for the 2021 Lexus RC 350 F Sport. Understanding the different options will help you make an informed decision and choose the system that's right for you.

• Axle-Back Exhaust: This is the most common and affordable type of exhaust upgrade. It replaces the section of the exhaust system from the rear axle to the exhaust tips. Axle-back systems are relatively easy to install and can provide a noticeable improvement in sound. They're a great option if you're looking for a simple and cost-effective way to enhance your car's exhaust note. Expect to pay anywhere from $300 to $800 for a decent axle-back system.
• Cat-Back Exhaust: A cat-back exhaust replaces the entire exhaust system from the catalytic converters back. This includes the mid-pipe, muffler, and exhaust tips. Cat-back systems offer more significant performance gains than axle-back systems, as they improve exhaust flow throughout the entire system. They also tend to have a more aggressive sound. This type of exhaust typically ranges between $800 and $1500.
• Header-Back Exhaust (Full Exhaust): This is the most comprehensive exhaust upgrade, replacing everything from the exhaust manifold (headers) to the exhaust tips. Header-back systems offer the greatest potential for performance gains, as they completely optimize exhaust flow from the engine. However, they are also the most expensive and complex to install. These can easily run you $1500+. Keep in mind that replacing the headers may also require modifications to your engine management system.

Key Considerations When Choosing an Exhaust

Okay, so you know the types of exhaust available. Now let's talk about some important factors to consider when making your choice. There's more to it than just picking the loudest one!

• Sound Level and Tone: Exhaust sound is subjective, so it's important to choose an exhaust that matches your personal taste. Do you want a deep, throaty rumble or a high-pitched scream? Are you okay with some drone at highway speeds, or do you want a system that's relatively quiet when cruising? Listen to sound clips online before you buy to get a better idea of what each exhaust sounds like. YouTube is your best friend here!
• Material: Exhaust systems are typically made from either aluminized steel, stainless steel, or titanium. Aluminized steel is the most affordable option, but it's also the least durable and prone to rust. Stainless steel is a good balance of price and durability, offering excellent corrosion resistance. Titanium is the lightest and most expensive option, offering superior strength and corrosion resistance. If you live in a snowy area with lots of road salt, stainless steel is definitely the way to go.
• Fitment: Make sure the exhaust system you choose is specifically designed for the 2021 Lexus RC 350 F Sport. A universal exhaust system might require modifications to fit properly, which can be a hassle. Check the manufacturer's website or consult with a professional installer to ensure proper fitment.
• Installation: Axle-back exhausts are typically easy to install yourself, while cat-back and header-back systems may require professional installation. If you're not comfortable working on cars, it's best to leave the installation to a qualified mechanic. Factor in the cost of installation when budgeting for your exhaust upgrade.
• Legality: Be aware of local laws regarding exhaust noise levels. Some states and municipalities have strict regulations on aftermarket exhaust systems. Make sure the exhaust you choose is street legal in your area to avoid getting a ticket. Nobody wants a hefty fine just for having a cool-sounding exhaust!

• Read the Instructions: This might seem obvious, but it's important to read the installation instructions carefully before you start. Make sure you understand the steps involved and have all the necessary tools. Rushing through the installation process can lead to mistakes and headaches.
• Use the Right Tools: Using the right tools will make the job much easier and prevent damage to your car. You'll need a socket set, wrenches, a jack, jack stands, and possibly a penetrating oil to loosen rusty bolts. Don't try to MacGyver it with whatever you have lying around the garage.
• Wear Safety Gear: Protect yourself by wearing safety glasses and gloves. Exhaust systems can be hot and dirty, and you don't want to get burned or cut. Safety first, kids!.
• Loosen Rusty Bolts: If your car is a few years old, the exhaust bolts may be rusty and difficult to remove. Apply penetrating oil to the bolts and let it soak for a few minutes before trying to loosen them. You might need to use a breaker bar or a torch to get them off.
• Use Jack Stands: Never work under a car that is only supported by a jack. Use jack stands to support the car safely. Your life is worth more than saving a few minutes.
• Tighten Bolts Properly: Use a torque wrench to tighten the exhaust bolts to the manufacturer's specifications. Overtightening can damage the bolts or the exhaust system. Undertightening can cause leaks..
• Check for Leaks: After you've installed the exhaust, start the car and check for exhaust leaks. Listen for hissing sounds or feel for exhaust fumes escaping from the joints. If you find a leak, tighten the bolts or replace the gasket.
