So, you're thinking about beefing up your Infiniti G35 sedan with a dual exhaust system, huh? Awesome choice! A dual exhaust can seriously transform your G35, not just in terms of performance but also in giving it that aggressive, head-turning sound. This guide will walk you through everything you need to know about upgrading to a dual exhaust system, from the benefits to the installation process and even picking the right kit. Let's dive in!

Why Go Dual Exhaust on Your G35 Sedan?

Let's get straight to the point: why should you even bother with a dual exhaust system? Well, guys, there are several compelling reasons. First off, performance! The stock exhaust system on the G35, while decent, is designed with a focus on reducing noise and emissions, which can restrict the engine's ability to breathe freely. A dual exhaust system, on the other hand, typically features larger diameter piping and less restrictive mufflers. This allows exhaust gases to exit the engine more efficiently, which can translate to noticeable gains in horsepower and torque.

Think of it like this: Imagine trying to run a marathon while breathing through a tiny straw. Not very efficient, right? The same principle applies to your engine. By upgrading to a dual exhaust, you're essentially giving your engine a bigger, less restrictive "straw" to breathe through, allowing it to perform at its peak. Besides the performance boost, a dual exhaust also enhances the sound of your G35. The stock exhaust note is fairly tame, but a dual exhaust can unleash a deep, throaty roar that will make your car sound like a true performance machine.

And let's be honest, who doesn't love a good sounding exhaust? Furthermore, a dual exhaust system can also improve the overall look of your G35. Many aftermarket systems feature polished stainless steel tips that add a touch of aggression and sportiness to the rear of the car. It's a visual upgrade that complements the performance and sound enhancements. Finally, upgrading to a dual exhaust can also increase your car's resale value. A well-maintained G35 with tasteful modifications like a dual exhaust is often more appealing to potential buyers, especially those who are looking for a performance-oriented vehicle. So, whether you're looking for more power, a better sound, a more aggressive look, or increased resale value, a dual exhaust system is a worthwhile upgrade for your Infiniti G35 sedan.

Choosing the Right Dual Exhaust System

Alright, so you're sold on the idea of a dual exhaust. Now comes the fun (and sometimes overwhelming) part: choosing the right system for your G35. The market is flooded with options, each with its own set of features, benefits, and price points. But don't worry, we'll break it down to make the decision process a little easier. First and foremost, consider your budget. Dual exhaust systems can range in price from a few hundred dollars to well over a thousand, depending on the brand, materials, and features. Determine how much you're willing to spend before you start shopping, as this will help you narrow down your options. Next, think about the sound you're after. Do you want a deep, aggressive roar, or something a little more subtle? Some systems are designed to be loud and attention-grabbing, while others are engineered for a more refined and sophisticated sound. Listen to sound clips online or, if possible, try to hear the exhaust in person before you make a decision.

Material is another important factor to consider. Most aftermarket exhaust systems are made from either aluminized steel or stainless steel. Aluminized steel is more affordable but is also more prone to rust and corrosion. Stainless steel, on the other hand, is more durable and resistant to corrosion, making it a better long-term investment. However, stainless steel systems are typically more expensive. Also, pay attention to the diameter of the exhaust piping. Larger diameter piping will generally result in better performance, but it can also increase the exhaust noise. A good rule of thumb is to stick with a diameter that is slightly larger than the stock piping, but not so large that it causes excessive drone or resonance. The brand reputation is also important when choosing an exhaust system. Stick with reputable brands that have a proven track record of producing high-quality products. Read reviews online and ask for recommendations from other G35 owners. This will help you avoid getting stuck with a poorly made or ill-fitting exhaust system.

Finally, consider the overall design and aesthetics of the exhaust system. Do you like the look of the exhaust tips? Are they the right size and shape for your car? Do they complement the overall style of your G35? After all, the exhaust system is a visible part of your car, so you want to make sure it looks good. By considering all of these factors, you can narrow down your options and choose the dual exhaust system that is right for your Infiniti G35 sedan.

Installation: DIY or Professional?

Okay, you've picked out your dream dual exhaust system. Now, the big question: are you going to install it yourself, or are you going to leave it to the professionals? This really depends on your mechanical skills, your available tools, and your tolerance for frustration. If you're mechanically inclined and have some experience working on cars, you might be able to tackle the installation yourself. There are plenty of online tutorials and videos that can guide you through the process. However, keep in mind that it can be a time-consuming and challenging job, especially if you've never done it before. You'll need a good set of tools, including a wrench set, a socket set, a jack and jack stands, and possibly a saw or cutting tool to remove the old exhaust system. You'll also need to be prepared to deal with rusty bolts, tight spaces, and the occasional unexpected problem.

On the other hand, if you're not comfortable working on cars or if you simply don't have the time, it's best to leave the installation to a professional mechanic. A professional will have the experience, tools, and expertise to install the exhaust system quickly and correctly. They can also identify and address any potential problems that might arise during the installation process. While it will cost more to have a professional install the exhaust system, it can save you a lot of time, hassle, and potential headaches in the long run. Ultimately, the decision of whether to DIY or go professional is a personal one. Weigh the pros and cons carefully and choose the option that you're most comfortable with.

Step-by-Step: Installing Your Dual Exhaust (DIY Guide)

So, you're the adventurous type and decided to tackle the installation yourself? Awesome! Here's a general step-by-step guide to help you through the process. Keep in mind that this is a general guide, and the specific steps may vary depending on the make and model of your exhaust system. Always refer to the manufacturer's instructions for the most accurate and up-to-date information. First, gather your tools. You'll need a wrench set, a socket set, a jack and jack stands, penetrating oil, a saw or cutting tool (if needed), and possibly a rubber mallet. Safety first! Put on safety glasses and gloves to protect yourself from flying debris and sharp edges. Jack up your G35 and secure it on jack stands. Make sure the car is stable and won't fall off the stands. Spray penetrating oil on all the bolts and connections of the old exhaust system. This will help loosen them up and make them easier to remove. Let the penetrating oil soak in for at least 15-20 minutes.

Next, disconnect the oxygen sensors from the exhaust system. Be careful not to damage the sensors. Unbolt the old exhaust system from the catalytic converters or exhaust manifolds. You may need to use a saw or cutting tool to cut the old exhaust system if it's stuck or if the bolts are too rusted to remove. Carefully remove the old exhaust system from the car. Be sure to support it as you remove it to prevent it from falling and causing damage. Now, it is time to install the new dual exhaust system. Start by bolting the new exhaust pipes to the catalytic converters or exhaust manifolds. Make sure the connections are tight and secure. Install the mufflers and exhaust tips. Adjust the position of the mufflers and tips to ensure they are properly aligned and look good. Reconnect the oxygen sensors to the new exhaust system. Lower the car from the jack stands. Start the engine and check for exhaust leaks. If you find any leaks, tighten the connections until the leaks are gone. Finally, take your G35 for a test drive and enjoy the new sound and performance of your dual exhaust system!

Maintaining Your Dual Exhaust System

Congratulations, you've successfully installed your dual exhaust system! But the job's not quite over yet. To keep your exhaust system performing at its best and looking its best, you'll need to perform some regular maintenance. First, inspect your exhaust system regularly for any signs of damage or corrosion. Check for rust, cracks, dents, or loose connections. If you find any problems, address them promptly to prevent them from getting worse. Clean your exhaust tips regularly to remove dirt, grime, and exhaust buildup. You can use a metal polish or a dedicated exhaust tip cleaner to keep them looking shiny and new. Tighten all the bolts and connections periodically to ensure they are secure. Exhaust vibrations can cause the bolts to loosen over time, which can lead to exhaust leaks. Also, avoid driving through deep water or snow, as this can cause the exhaust system to rust and corrode more quickly. If you do drive through water or snow, rinse the exhaust system with fresh water as soon as possible.

If you live in an area with harsh winters and salted roads, consider applying a rust inhibitor to the exhaust system to protect it from corrosion. Finally, have your exhaust system inspected by a professional mechanic at least once a year. A mechanic can identify any potential problems that you might have missed and perform any necessary repairs or maintenance. By following these simple maintenance tips, you can keep your dual exhaust system performing at its best and looking its best for years to come.

Conclusion
