Hey guys! If you're rolling around in a sleek Infiniti G35 Sedan, you're already familiar with a car that blends performance and luxury. But are you looking to take things up a notch? One of the most popular upgrades for the G35 is a dual exhaust system. Not only does it add a serious visual upgrade, but it can also enhance the sound and, in some cases, even boost your horsepower. In this comprehensive guide, we'll dive deep into everything you need to know about Infiniti G35 sedan dual exhaust systems, from the benefits and different types available to the installation process and what to consider before making a purchase. So, buckle up, because we're about to explore the world of G35 exhaust systems!

Why Upgrade to a Dual Exhaust for Your Infiniti G35 Sedan?

So, why bother with a dual exhaust system for your Infiniti G35 sedan? Well, there are several compelling reasons. First and foremost, aesthetics: let's face it, a dual exhaust looks fantastic! It gives your G35 a more aggressive, sporty stance that turns heads. The symmetrical design, with exhaust tips on both sides of the rear bumper, instantly elevates the car's visual appeal. It signals that this isn't just a regular sedan; it's something special. Another major benefit is the sound. The stock exhaust on the G35, while not terrible, is often pretty muted. A dual exhaust system can unleash a more throaty, aggressive growl that perfectly complements the car's performance capabilities. Whether you're cruising down the highway or hitting the gas on the open road, the enhanced sound will make every drive more engaging and enjoyable. Some dual exhaust systems are designed to improve performance. By reducing backpressure, they can help the engine breathe more freely, potentially leading to small but noticeable horsepower and torque gains. While the gains might not be massive, every little bit helps, especially if you're a performance enthusiast. Beyond the visual and auditory enhancements, a high-quality dual exhaust system can actually increase your car's value. If you ever decide to sell your G35, the upgraded exhaust can be a selling point, attracting potential buyers who are looking for a car that's already been modified and improved. It's an investment that can pay off in the long run!

But let's not forget the emotional connection. Upgrading your car is a way of personalizing it and making it your own. It's a statement about your taste and your passion for cars. It's about enjoying the experience of driving and making your G35 even more fun to drive. Also the exhaust customization allows you to tailor the sound and performance to your liking. Whether you're after a loud and proud roar or a more subtle, refined rumble, you can choose a system that perfectly matches your preferences. There's a wide range of options available, allowing you to fine-tune the exhaust note and performance characteristics to your specific needs. In a nutshell, a dual exhaust system is more than just a cosmetic upgrade; it's a way to enhance your driving experience, make your G35 stand out, and express your passion for cars.

Types of Dual Exhaust Systems for the Infiniti G35 Sedan

Alright, let's get into the nitty-gritty: what types of dual exhaust systems are available for the Infiniti G35 sedan? You've got several options to choose from, each with its own pros, cons, and price points. Understanding these differences will help you make the best decision for your needs and budget. The most common type is a cat-back exhaust system. This replaces the exhaust components from the catalytic converters (the “cats”) back to the tailpipes. This is a popular choice because it offers a good balance of performance gains, sound improvement, and relative ease of installation. Cat-back systems typically include the muffler, resonators (if any), and the piping that connects everything together. They're often designed to bolt directly onto the existing exhaust flanges, making installation relatively straightforward, even for DIY enthusiasts. These systems usually provide a noticeable increase in sound, and some may offer a slight increase in horsepower. Another option is a axle-back exhaust system. This system replaces only the components from the rear axle back, including the muffler and tailpipes. Axle-back systems are generally less expensive and easier to install than cat-back systems, making them a great choice for those who want a simple upgrade without a lot of hassle. They typically focus on sound enhancement and aesthetics, offering a more aggressive exhaust note and a sportier look. Performance gains are usually minimal with an axle-back system, but the sound upgrade can be significant. Then there are full exhaust systems. These are the most comprehensive option, replacing the entire exhaust system from the headers (the part connected to the engine) all the way back to the tailpipes. This includes the headers, catalytic converters, mid-pipes, muffler, and tailpipes. Full exhaust systems offer the greatest potential for performance gains, as they optimize the entire exhaust flow path. However, they are also the most expensive and complex to install. They often require welding and may not be street-legal in all areas, depending on the emissions regulations.

If you're really serious about performance, you might consider long tube headers. These are a type of header that replaces the factory exhaust manifold with longer, more free-flowing pipes. Long tube headers can significantly improve exhaust flow, resulting in substantial horsepower and torque gains. However, they are generally not street-legal and can be difficult to install, requiring a high level of mechanical skill. When you're shopping for a dual exhaust system, keep an eye on the materials. Stainless steel is the preferred choice, as it's durable, rust-resistant, and can withstand high temperatures. Aluminized steel is a more affordable option, but it's not as resistant to rust and may not last as long. The diameter of the piping is also important. Larger diameter pipes can improve exhaust flow, but they might not be necessary for all applications. Consider your performance goals and the overall setup of your car when choosing the pipe diameter. The muffler design will greatly influence the sound of the exhaust. There are various types of mufflers, including straight-through, chambered, and absorption-style mufflers. Each type produces a different sound, so research the different options to find one that matches your preferences.

Installation: How to Install a Dual Exhaust on Your Infiniti G35 Sedan

So, you've chosen your dream dual exhaust system. Now comes the installation! While the specifics will vary depending on the type of system you've chosen and the manufacturer, the general steps are pretty consistent. Before you start, gather your tools. You'll likely need a jack and jack stands to safely lift the car, wrenches, sockets, a pry bar, penetrating oil (for stubborn bolts), and possibly a cutting tool (if you're removing the existing exhaust). Make sure you have all the necessary components of your new system, including pipes, mufflers, clamps, and any hardware. Safety first, guys! Always work on a level surface and wear safety glasses and gloves. If you're not comfortable working on cars, it's best to have a professional install the system. Begin by lifting the car and securing it with jack stands. Never work under a car supported only by a jack! Next, remove the old exhaust system. This may involve unbolting the existing exhaust components, which can sometimes be a challenge, especially if the bolts are corroded. Use penetrating oil to loosen stubborn bolts. You might need to cut the old exhaust pipes if they're welded or if they're difficult to remove. Once the old system is out of the way, begin installing the new system. Start by connecting the pipes to the catalytic converters or headers (depending on the type of system). Use the provided clamps or hardware to secure the pipes. Make sure all connections are tight. Next, install the muffler(s) and any resonators. Align the system properly and make sure the exhaust tips are positioned correctly. Don't overtighten the clamps, as this can damage the pipes. Double-check all connections and hardware to ensure everything is secure. Make sure the system isn't touching any parts of the car, such as the driveshaft or fuel lines. Start the car and listen for any leaks. If you hear any hissing or unusual sounds, check the connections and tighten the clamps as needed. Take your car for a test drive and listen for any rattles or noises. Make any necessary adjustments. The installation process can vary, depending on the type of exhaust system. Cat-back systems are generally easier to install than full exhaust systems, which may require welding. If you're not comfortable with any of these steps, it's always best to have a professional install the system. They have the tools, expertise, and experience to do the job right. Installing a dual exhaust system is a satisfying project that can significantly improve your G35's performance, sound, and appearance. Just take your time, follow the instructions carefully, and ensure all connections are secure. And remember, if you're ever in doubt, consult a professional!

Choosing the Right Dual Exhaust System

Alright, so you're ready to pick out your dual exhaust system. Awesome! But where do you start? With so many options out there, it can seem overwhelming. Let's break down the key factors to consider to help you make the best choice for your Infiniti G35 sedan. First and foremost, consider your budget. Dual exhaust systems range in price from a few hundred dollars to over a thousand dollars, depending on the brand, materials, and features. Set a budget before you start shopping to narrow down your options. Next, think about your performance goals. If you're looking for maximum power gains, a full exhaust system with headers might be the best choice. However, if you're primarily interested in sound and aesthetics, a cat-back or axle-back system might be sufficient. Research different brands and models, and read reviews to get an idea of the performance gains people are experiencing. The sound is a major factor. Different mufflers and exhaust designs produce different sounds. Some systems are designed to be loud and aggressive, while others offer a more subtle, refined sound. Listen to sound clips and watch videos to get a feel for what each system sounds like. The aesthetics are important. Consider the style of the exhaust tips and the overall appearance of the system. Do you want a polished stainless steel finish? Black coated tips? Choose a system that complements the look of your G35. Consider the material of the exhaust. Stainless steel is the best option for durability and corrosion resistance, but it's also more expensive. Aluminized steel is a more affordable alternative, but it's not as resistant to rust. Also, check the reviews before making a purchase. Read what other G35 owners have to say about the different systems. Pay attention to the quality, fitment, sound, and performance of each system.
