But if you’re looking to take your ride to the next level, upgrading the exhaust system is a fantastic place to start. Buckle up as we dive into the world of the 370z exhaust system, exploring everything from the basics to the best options available. Whether you’re aiming for enhanced performance, a throatier growl, or just some good ol’ car enthusiast fun, this guide has got you covered.

Understanding the 370z Exhaust System

The exhaust system in your Nissan 370z plays a crucial role in the car’s overall performance. It’s not just about making noise—though, let’s be honest, that’s a big part of the appeal. The exhaust system impacts everything from horsepower to fuel efficiency. So, what exactly does it do?

The Role of an Exhaust System

In simple terms, the exhaust system is responsible for directing the gases produced by your engine away from the vehicle. These gases are a byproduct of the internal combustion process. An efficient exhaust system minimizes the noise, reduces the emission of harmful gases, and enhances the performance of your car by allowing the engine to breathe better.

Components of a 370z Exhaust System

To get a better grasp of the 370z exhaust system, let’s break down its main components:

  1. Exhaust Manifold: Collects exhaust gases from the engine cylinders and directs them into the exhaust pipe.
  2. Catalytic Converter: Reduces the toxicity of emissions by converting harmful gases into less harmful substances.
  3. Resonator: Reduces noise and smoothens the exhaust flow.
  4. Muffler: Further decreases the noise produced by the exhaust gases.
  5. Exhaust Pipe: Channels the gases out of the vehicle.

Benefits of Upgrading Your 370z Exhaust System

Upgrading your 370z exhaust system can offer a host of benefits. Here are some compelling reasons to consider making the switch:

Enhanced Performance

One of the most significant advantages of an upgraded exhaust system is improved performance. A high-quality aftermarket exhaust can increase your car’s horsepower and torque by allowing the engine to expel exhaust gases more efficiently.

Better Fuel Efficiency

Who doesn’t want to save a few bucks on gas? A well-designed exhaust system reduces the engine’s workload, leading to better fuel economy. It’s a win-win situation—more power and fewer stops at the pump.

Improved Sound

Let’s face it—part of the thrill of driving a sports car is the sound. An upgraded exhaust system can give your 370z a more aggressive and satisfying growl. Whether you prefer a deep rumble or a high-pitched roar, there’s an exhaust system out there to match your style.


Upgrading your exhaust system isn’t just about function; it’s also about form. Many aftermarket systems come with sleek, polished tips that can enhance the look of your car’s rear end.

Types of 370z Exhaust Systems

When it comes to choosing an exhaust system for your 370z, there are several options available. Here are the main types you might consider:

Cat-Back Exhaust Systems

A cat-back exhaust system replaces everything from the catalytic converter back to the muffler and exhaust tip. This type of system is popular among car enthusiasts because it offers a good balance of performance improvement and cost.

Axle-Back Exhaust Systems

An axle-back exhaust system replaces only the components from the rear axle to the exhaust tip. It’s generally less expensive than a cat-back system and still offers some performance and sound enhancements.

Header-Back Exhaust Systems

A header-back system replaces the entire exhaust system from the headers to the exhaust tip. This is the most comprehensive and expensive option, offering the most significant performance gains.

Turbo-Back Exhaust Systems

If your 370z is turbocharged, a turbo-back exhaust system might be the way to go. This type of system replaces everything from the turbocharger to the exhaust tip, optimizing the performance of your turbocharged engine.
