So, you're looking to upgrade the exhaust on your Infiniti G37 Coupe? Awesome! You've come to the right place. The G37 Coupe is already a fantastic car, but let's be honest, the stock exhaust note can be a little…underwhelming. We're going to dive deep into the world of G37 exhaust systems, helping you find the perfect sound to match your style and turn heads wherever you go. Whether you're after a deep, aggressive growl or a refined, sporty tone, we've got you covered.

Why Upgrade Your G37 Coupe's Exhaust?

Before we jump into specific exhaust options, let's quickly cover why upgrading your exhaust is a popular and worthwhile modification for the G37 Coupe. Here's the breakdown:

• Improved Sound: This is the most obvious reason, right? A new exhaust can completely transform the sound of your G37, giving it a more aggressive, sporty, and exciting tone. You can ditch the quiet stock exhaust and unleash the true potential of that VQ37VHR engine.
• Increased Performance: While the power gains from an exhaust upgrade alone might not be massive, they're definitely noticeable. A less restrictive exhaust system allows your engine to breathe more freely, resulting in a slight increase in horsepower and torque. Think of it as letting your engine exhale more easily.
• Enhanced Aesthetics: Many aftermarket exhaust systems look fantastic, with polished stainless steel tips and aggressive designs that can really enhance the look of your G37's rear end. It's a visual upgrade that complements the improved sound.
• Weight Reduction: Some aftermarket exhaust systems are lighter than the factory exhaust, which can contribute to improved handling and overall performance. Every little bit helps, am I right?

Key Factors to Consider When Choosing an Exhaust

Alright, guys, let's get into the nitty-gritty. Choosing the right exhaust for your G37 Coupe involves considering several factors to ensure you get the sound and performance you're after. Here's what you need to keep in mind:

• Sound Preference: This is the big one. What kind of sound are you looking for? Do you want a deep, rumbling growl, a high-pitched exotic scream, or something in between? Listen to sound clips online and try to find examples that match your taste.
• Exhaust Type: There are several different types of exhaust systems available for the G37 Coupe, each with its own characteristics:
  • Axle-Back Exhaust: This is the most common and affordable option. It replaces the mufflers and exhaust tips, primarily focusing on improving the sound. Performance gains are typically minimal.
  • Cat-Back Exhaust: This replaces everything from the catalytic converters back, including the mid-pipe and mufflers. Cat-back systems offer a better balance of sound and performance improvements.
  • Full Exhaust System (Headers, Cats, and Cat-Back): This is the most comprehensive and expensive option. It replaces the entire exhaust system from the engine headers to the exhaust tips, offering the greatest potential for performance gains and a significant change in sound. This is for the serious enthusiasts!
• Material: Exhaust systems are typically made from stainless steel or aluminized steel. Stainless steel is more durable and resistant to corrosion, making it the better choice for long-term reliability. Aluminized steel is more affordable but may rust over time.
• Pipe Diameter: The diameter of the exhaust piping affects the sound and performance. Larger diameter pipes generally result in a louder, more aggressive sound and can improve exhaust flow, but too large of a diameter can actually hurt performance by reducing backpressure.
• Resonators and Mufflers: Resonators and mufflers are used to control the sound level and tone of the exhaust. Resonators help to eliminate unwanted frequencies and drone, while mufflers reduce the overall volume. The design and construction of these components significantly impact the final sound.
• Budget: Exhaust systems can range in price from a few hundred dollars to several thousand dollars. Determine your budget beforehand to narrow down your options.
