So, you're looking to upgrade your Infiniti G37 Coupe's exhaust system, huh? Awesome choice! A new exhaust can seriously transform your driving experience, not just in terms of power, but also with a sweet, aggressive sound. Let's dive into everything you need to know to make the right decision. We will cover everything from brands and types to installation and overall value.

Why Upgrade Your G37 Coupe Exhaust?

Before we get into the nitty-gritty, let's talk about why you should even bother upgrading your exhaust in the first place. The stock exhaust systems on most cars, including the G37, are designed with a focus on noise reduction and cost-effectiveness. This often means they're restrictive, hindering the engine's ability to breathe freely. Upgrading your exhaust can unlock several benefits:

  • Increased Horsepower and Torque: A less restrictive exhaust allows exhaust gases to flow more easily, reducing backpressure on the engine. This can result in noticeable gains in horsepower and torque, especially in the mid-range and top-end.
  • Improved Throttle Response: With less backpressure, the engine can respond more quickly to throttle inputs, making the car feel more responsive and engaging to drive. It's like waking up the sleeping beast!
  • Enhanced Sound: Let's be honest, this is a big one for many of us. An aftermarket exhaust can give your G37 a deeper, more aggressive exhaust note. From a subtle rumble to a full-on roar, the choice is yours.
  • Weight Reduction: Many aftermarket exhaust systems are made from lighter materials like stainless steel or titanium, which can reduce the overall weight of the car. This can improve handling and acceleration.
  • Aesthetic Appeal: A shiny new exhaust system can add a touch of visual flair to the rear of your car, especially if you opt for upgraded exhaust tips.

Types of Infiniti G37 Coupe Exhaust Systems

Alright, now that you're convinced (or at least seriously considering) an exhaust upgrade, let's explore the different types of systems available for your G37 Coupe. Knowing the difference between these types is crucial for making an informed decision.

Cat-Back Exhaust Systems

A cat-back exhaust replaces everything from the catalytic converters to the exhaust tips. This is often the most popular choice for G37 owners because it offers a good balance of performance, sound, and affordability. Cat-back systems typically include a mid-pipe, muffler, and exhaust tips. They are generally easier to install than other types of exhaust systems, as they bolt directly onto the existing catalytic converters.

  • Pros: Good balance of performance and sound, relatively easy to install, and generally more affordable than other options.
  • Cons: Power gains may not be as significant as with a full exhaust system.

Axle-Back Exhaust Systems

An axle-back exhaust is the simplest and most budget-friendly option. It only replaces the components from the rear axle back, typically including the muffler and exhaust tips. Axle-back systems are primarily focused on improving the sound of your exhaust, with minimal performance gains.

  • Pros: Most affordable option, easy to install, and offers a noticeable improvement in exhaust sound.
  • Cons: Minimal performance gains, may not be as durable as other systems.

Full Exhaust Systems (Headers, High-Flow Cats, Cat-Back)

A full exhaust system, also known as a turbo-back or header-back system, replaces everything from the engine's exhaust manifold (headers) to the exhaust tips. This is the most comprehensive and expensive option, but it also offers the greatest potential for performance gains. Full exhaust systems typically include headers, high-flow catalytic converters, a mid-pipe, a muffler, and exhaust tips. However, keep in mind that replacing the catalytic converters may not be street legal in some areas, so be sure to check your local regulations before making this modification.

  • Pros: Maximum performance gains, significant improvement in exhaust sound, and can dramatically improve the overall driving experience.
  • Cons: Most expensive option, more difficult to install, and may not be street legal in some areas.

Key Considerations When Choosing an Exhaust System

Okay, so you know the types of exhausts, but how do you choose the right one? Here are some crucial factors to consider:

Sound

Sound is subjective, but it's arguably the most important factor for many buyers. Do you want a deep, throaty rumble, or a high-pitched, aggressive scream? Do you want something that's relatively quiet at idle and cruising speeds, or are you okay with a louder system that's always noticeable? Listen to sound clips online before you buy.

Performance

Are you primarily looking for increased horsepower and torque, or are you more interested in sound and aesthetics? If performance is your top priority, you'll want to consider a full exhaust system with headers and high-flow cats. However, if you're on a budget, a cat-back system can still provide a noticeable improvement in performance.

Material and Build Quality

Exhaust systems are typically made from stainless steel, aluminized steel, or titanium. Stainless steel is the most common choice because it offers a good balance of durability, corrosion resistance, and affordability. Aluminized steel is cheaper but more prone to rust. Titanium is the lightest and most expensive option, offering excellent durability and corrosion resistance.

Price

Exhaust systems can range in price from a few hundred dollars to several thousand dollars, depending on the type, material, and brand. Set a budget before you start shopping, and stick to it.

Installation

How comfortable are you with installing the exhaust system yourself? Axle-back systems are generally the easiest to install, while full exhaust systems can be more challenging and may require professional installation. Factor in the cost of installation when budgeting for your exhaust upgrade.

Brand Reputation

Stick with reputable brands that are known for producing high-quality exhaust systems. Some popular brands for the G37 include:

  • Invidia: Known for their high-quality stainless steel exhausts and aggressive sound.
  • ARK Performance: Offers a wide range of exhaust systems, from mild to wild.
  • Stillen: A well-established brand with a reputation for performance and reliability.
  • Megan Racing: A more budget-friendly option that still offers good performance and sound.

Installation Tips

So, you've picked out your dream exhaust, and now it's time to install it. Here are a few tips to make the process smoother:

  • Gather Your Tools: Make sure you have all the necessary tools before you start, including wrenches, sockets, a jack, jack stands, penetrating oil, and a torque wrench.
  • Safety First: Always wear safety glasses and gloves when working on your car. And never work under a car that is only supported by a jack. Use jack stands!
  • Penetrating Oil is Your Friend: Spray all the bolts and nuts with penetrating oil a few hours before you start working. This will make them much easier to remove.
  • Take Your Time: Don't rush the installation process. Take your time and make sure everything is properly aligned and tightened.
  • Torque to Spec: Use a torque wrench to tighten all the bolts and nuts to the manufacturer's specifications. This will prevent leaks and ensure that the exhaust system is properly secured.
  • Watch Videos: There are tons of great videos available online that show you how to install an exhaust system on a G37. Watch a few of them before you start to get a better understanding of the process.

Caring for Your New Exhaust

Once your new exhaust is installed, you'll want to take care of it to ensure it lasts for years to come. Here are a few tips:

  • Regular Cleaning: Clean your exhaust system regularly with soap and water to remove dirt, grime, and road salt. This is especially important if you live in an area with harsh winters.
  • Polishing: If your exhaust system is made from stainless steel, you can polish it periodically to keep it looking shiny and new. Use a stainless steel polish and a soft cloth.
  • Inspect Regularly: Inspect your exhaust system regularly for any signs of damage, such as rust, cracks, or leaks. If you notice any problems, address them immediately to prevent further damage.

Conclusion

Upgrading your Infiniti G37 Coupe's exhaust system is a fantastic way to improve its performance, sound, and appearance. By understanding the different types of systems available, considering your priorities, and following these tips, you can choose the perfect exhaust to unleash the true potential of your G37.
