Subaru Brz Power Gains: How a Wrx Exhaust Boosts Output by 15 Hp for $500

by

The Subaru BRZ is known for its lightweight design and precise handling, making it a favorite among driving enthusiasts. However, many owners seek to enhance the performance of their vehicle. One effective way to achieve this is by upgrading the exhaust system. In this article, we will explore how a WRX exhaust can boost the output of a BRZ by 15 horsepower for around $500.

Understanding the Subaru BRZ and WRX Exhaust Systems

The Subaru BRZ is equipped with a naturally aspirated 2.4-liter flat-four engine, which offers a balanced power delivery. On the other hand, the WRX features a turbocharged engine that delivers more power and torque. The exhaust systems of these two vehicles differ significantly, leading to different performance characteristics.

Key Differences in Exhaust Design

The WRX exhaust system is designed to handle higher exhaust flow due to the turbocharged engine. This design includes:

  • Larger diameter piping
  • More efficient muffler design
  • Better flow characteristics

These features allow for improved exhaust flow, which can significantly enhance the performance of the BRZ when a WRX exhaust is installed.

Benefits of Installing a WRX Exhaust on a BRZ

Upgrading to a WRX exhaust system offers several advantages for BRZ owners looking to increase horsepower and improve overall performance. Some of the key benefits include:

  • Increased horsepower: Expect a gain of around 15 HP.
  • Improved throttle response: Enhanced exhaust flow leads to quicker acceleration.
  • Better sound: A WRX exhaust provides a more aggressive and sporty sound.
  • Weight reduction: Many aftermarket exhausts are lighter than stock components.

Cost-Effectiveness

For approximately $500, the performance gains from a WRX exhaust are substantial. Compared to other performance upgrades, this is a relatively low-cost modification that yields noticeable results.

Installation Process

Installing a WRX exhaust on a BRZ can be done with basic tools and some mechanical knowledge. Here’s a brief overview of the process:

  • Gather necessary tools: jack stands, socket set, and wrenches.
  • Lift the vehicle: Ensure safety by using jack stands.
  • Remove the stock exhaust: Unbolt the existing exhaust system from the headers and hangers.
  • Install the WRX exhaust: Position the new exhaust and secure it with bolts and hangers.
  • Check for leaks: Start the engine and inspect for any exhaust leaks.

With the right tools and care, this upgrade can be completed in a few hours.

Potential Drawbacks

While there are many benefits to installing a WRX exhaust on a BRZ, there are potential drawbacks to consider:

  • Increased noise: The more aggressive sound may not be suitable for all drivers.
  • Possible emissions issues: Ensure the exhaust complies with local regulations.
  • Fitment challenges: Some aftermarket parts may require adjustments for proper fit.

Conclusion

Upgrading to a WRX exhaust is a practical and effective way to boost the performance of a Subaru BRZ. With a modest investment of around $500, drivers can enjoy an increase of approximately 15 horsepower, improved throttle response, and a more exhilarating driving experience. As with any modification, it’s essential to weigh the benefits against potential drawbacks and ensure that the upgrade aligns with your personal preferences and driving style.
