3. Performance Gains

Upgrading to a high-performance exhaust system can significantly improve your BRZ's horsepower and torque output. When choosing an exhaust system, look out for features such as mandrel-bent tubing that allows smooth airflow without any restrictions or mufflers designed specifically to reduce backpressure.

Sound

When it comes to enhancing the performance and sound of your BRZ, upgrading the exhaust system is a crucial step. Not only does an upgraded exhaust system improve the overall performance of your vehicle, but it also adds a deeper and more aggressive tone to the engine.

But before we dive into the different types of BRZ exhaust systems available, let’s first understand how the sound of an exhaust system is produced.

Sound is created when exhaust gases are forced out of the engine and through the exhaust pipes. The vibration caused by this process creates waves that travel through the pipes and eventually exit through the muffler. The shape and design of these components play a significant role in determining how loud or quiet your BRZ will be.

Now, let’s take a closer look at some factors that affect the sound produced by an exhaust system:

1. Muffler Design

The muffler is one of the most critical components when it comes to controlling sound levels. It acts as a silencer by reducing high-frequency noise created by your engine. A straight-through or glasspack muffler produces a louder, more aggressive tone compared to chambered or bullet-style mufflers. However, keep in mind that too much noise can become irritating over time.

2. Exhaust Pipe Diameter

The diameter of your BRZ's exhaust pipes also affects its sound output. Smaller diameter pipes produce higher-pitched sounds while larger diameter pipes produce deeper tones. Upgrading to wider diameter pipes can give your car a more robust.

Performance

Performance is a crucial aspect when it comes to choosing the right exhaust system for your BRZ. A well-designed exhaust system can significantly improve the overall performance of your car, providing better acceleration, power, and fuel efficiency. In this section, we will discuss how each component of an exhaust system impacts the performance of your BRZ and how to choose the best options for maximum results.

1. Exhaust Manifold/Header:

The first component that affects the performance of your BRZ is the exhaust manifold or header. This part is responsible for collecting all the exhaust gases from each cylinder and directing them towards the rest of the exhaust system. A high-quality header can improve engine breathing by reducing backpressure and increasing airflow. This leads to improved horsepower, torque, and throttle response.

When choosing a header for your BRZ, look for one with equal-length tubes as it ensures balanced exhaust flow between cylinders and provides smoother power delivery throughout the RPM range.

2. Catalytic Converter:

The next essential component in an exhaust system is a catalytic converter. Its main job is to reduce harmful emissions by converting them into less toxic substances before they exit through the tailpipe. While catalytic converters are necessary for most vehicles to meet emission standards, they also create significant restriction in airflow due to their dense honeycomb structure.

To maintain a balance between performance and emissions control, you can opt for a high-flow catalytic converter or go with a test pipe if you don't have strict emission regulations in your area.

Style and Design

Style and design are key factors to consider when choosing an exhaust system for your BRZ. Not only do they impact the overall look of your vehicle, but they also play a role in its performance and sound. In this section, we will discuss the different styles and designs available for BRZ exhaust systems and how they can enhance both the aesthetics and functionality of your car.

1. Dual vs Single Exhaust Systems:

One of the first decisions you will need to make when selecting a BRZ exhaust is whether you want a dual or single exhaust system. A dual exhaust consists of two separate pipes that run from the engine to the rear of the vehicle, while a single exhaust has only one pipe that runs from the engine to the back. The main difference between these two options is in their appearance.

A dual exhaust system typically gives off a more aggressive and sporty look, as it is commonly associated with high-performance vehicles. It also allows for better airflow through the engine, resulting in improved horsepower and torque.
