Subaru Brz Intake and Exhaust Combo: Achieve 25 Hp Gains with a $1,200 Budget

by

The Subaru BRZ is known for its lightweight design and sporty handling, making it a favorite among car enthusiasts. One of the most effective ways to enhance the performance of your BRZ is through a combination of intake and exhaust modifications. This article will explore how you can achieve a significant power increase of 25 horsepower with a budget of $1,200.

Understanding the Basics

Before diving into the specifics of intake and exhaust upgrades, it’s important to understand how these components work together to improve engine performance. The intake system is responsible for drawing air into the engine, while the exhaust system expels exhaust gases. Optimizing both systems can lead to better airflow, increased horsepower, and improved throttle response.

Choosing the Right Intake System

When selecting an intake system for your Subaru BRZ, consider the following options:

  • Cold Air Intake: This type of intake draws cooler air from outside the engine bay, which can improve combustion efficiency.
  • Short Ram Intake: Positioned closer to the engine, this intake can provide quicker throttle response but may draw warmer air.
  • Aftermarket Filters: Upgrading to a high-flow air filter can enhance airflow without replacing the entire intake system.

Here are some popular intake systems that fit within the $1,200 budget:

  • K&N 69 Series Typhoon: Known for its excellent airflow and filtration, this system is a great choice for those seeking performance.
  • AEM Cold Air Intake: This intake offers a significant increase in horsepower and torque while maintaining a sleek design.
  • Injen SP Series: This system is designed for optimal performance and features a mandrel-bent aluminum construction.

Upgrading the Exhaust System

After upgrading the intake, the next step is to enhance the exhaust system. A performance exhaust can reduce back pressure and improve engine efficiency. Consider the following types of exhaust systems:

  • Cat-Back Exhaust: This system replaces the entire exhaust from the catalytic converter back, providing significant performance gains.
  • Axle-Back Exhaust: This option replaces the rear section of the exhaust system and is typically easier to install.
  • Header Upgrades: Replacing factory headers can further improve exhaust flow and boost horsepower.

Here are some exhaust systems that can help you achieve your horsepower goals:

  • Borla Cat-Back Exhaust: This system is known for its aggressive sound and performance improvements.
  • GReddy Supreme SP Exhaust: Offers a balanced tone and significant weight savings compared to the stock system.
  • Invidia Q300 Cat-Back Exhaust: Known for its deep tone and high-quality construction, this exhaust is a popular choice among enthusiasts.

Combining Intake and Exhaust Upgrades

Combining both intake and exhaust upgrades can maximize your performance gains. When installed together, these modifications create a synergistic effect that enhances airflow and engine efficiency. Here’s how to approach the combination:

  • Choose compatible parts that work well together for optimal performance.
  • Consider professional installation if you are not comfortable performing the upgrades yourself.
  • After installation, consider tuning your engine to fully realize the benefits of the new components.

Budget Breakdown

Staying within a $1,200 budget can be challenging, but it’s achievable with careful planning. Here’s a sample budget breakdown:

  • Intake System: $300 – $600
  • Exhaust System: $600 – $900
  • Installation Costs: $100 – $200 (if applicable)

Performance Gains and Expectations

After completing your intake and exhaust upgrades, you can expect noticeable performance improvements. Many enthusiasts report gains of up to 25 horsepower, depending on the specific components chosen and whether a tune is applied. Additionally, you may experience:

  • Improved throttle response
  • Enhanced engine sound
  • Better acceleration and overall performance

Conclusion

Upgrading the intake and exhaust systems of your Subaru BRZ is an effective way to enhance performance while staying within a reasonable budget. With careful selection of components and proper installation, achieving a 25 horsepower gain is within reach. Whether you’re a seasoned enthusiast or a newcomer to car modifications, these upgrades can significantly improve your driving experience.
