The Subaru Forester has gained a reputation as a versatile and capable vehicle, particularly among enthusiasts looking to enhance performance. One of the most effective ways to increase horsepower and improve exhaust flow is by upgrading the exhaust system. This article will compare turboback exhaust systems from two popular brands, Invidia and Borla, focusing on their potential to deliver over 20 wheel horsepower (whp).
Understanding Turboback Exhaust Systems
A turboback exhaust system replaces the entire exhaust setup from the turbocharger to the rear of the vehicle. This includes the downpipe, mid-pipe, and the rear section of the exhaust. Upgrading to a turboback system can significantly reduce back pressure, allowing the turbo to spool faster and produce more power. Additionally, these systems often improve sound and aesthetics.
Benefits of Upgrading to a Turboback System
- Increased horsepower and torque
- Improved turbo response
- Enhanced exhaust sound
- Better overall performance
- Potential for improved fuel efficiency
Invidia Turboback Exhaust System
The Invidia turboback exhaust system is known for its high-quality construction and performance gains. It features a 3-inch diameter piping, which helps to maximize exhaust flow. The system is made from stainless steel, ensuring durability and resistance to corrosion.
Key Features of Invidia
- 3-inch mandrel-bent piping for optimal flow
- High-flow catalytic converter
- Straight-through muffler design for aggressive sound
- Easy installation with all necessary hardware included
Performance Gains
Many users have reported gains of over 20 whp with the Invidia turboback system, especially when combined with an appropriate tune. The improved exhaust flow allows the turbo to operate more efficiently, resulting in better acceleration and overall performance.
Borla Turboback Exhaust System
Borla is another well-respected brand in the performance exhaust market. Their turboback exhaust system is designed to provide a balance of performance and sound. Like Invidia, Borla uses high-quality materials and engineering to ensure optimal performance.
Key Features of Borla
- 3-inch stainless steel piping for durability

Performance Gains
Users of the Borla turboback system have also reported significant power increases, often exceeding 20 whp. The system is designed to enhance turbo performance and provide a more engaging driving experience. With a proper tune, the Borla system can unlock the full potential of the Forester’s turbocharged engine.
Comparing Invidia and Borla
When comparing the Invidia and Borla turboback exhaust systems, several factors come into play. Both systems are engineered for performance, but they offer different sound profiles and aesthetic features.
Sound Comparison
The Invidia system is known for its loud, aggressive tone, making it a favorite among enthusiasts who enjoy a more pronounced exhaust note. In contrast, the Borla system provides a deeper, more refined sound that is still aggressive but may be more suitable for daily driving.
Build Quality
Both brands utilize high-quality stainless steel in their construction, ensuring longevity and resistance to rust and corrosion. The choice between them may come down to personal preference regarding design and finish.
Installation
Both systems are designed for easy installation with all necessary hardware included. However, some users have reported that the Invidia system may require slight adjustments for a perfect fit, whereas the Borla system typically fits without any modifications.
Conclusion
Upgrading to a turboback exhaust system is one of the most effective ways to enhance the performance of your Subaru Forester. Both the Invidia and Borla systems offer significant power gains, with many users reporting over 20 whp. Ultimately, the choice between the two will depend on personal preferences regarding sound, installation, and design.
Recommendations
