The Borla 11971 Crosstrek FT18-FT21 2.5L Flat 4 Exhaust System is a popular aftermarket exhaust option for the Subaru Crosstrek. This system is known for its performance gains and distinctive sound. Here are the pros and cons of investing in this exhaust system:

3. Distinctive Exhaust Note: The Borla system is renowned for its signature exhaust note, which is both loud and pleasing to many Subaru enthusiasts.

4. Quality Materials and Construction: Borla uses high-quality materials in the manufacturing process, including stainless steel for the piping to ensure durability and longevity.

5. Increased Fuel Efficiency: Borla claims their exhaust systems can improve fuel efficiency due to the reduction in exhaust backpressure and more efficient combustion.

1. Higher Cost: The Borla exhaust system is a premium option, and it comes with a higher price tag compared to other aftermarket exhausts.

2. Drone: Some drivers may find the Borla exhaust note loud and obtrusive at certain RPMs, particularly at idle or when cruising at low speeds.

3. Loud Exhaust: Depending on your preferences and the noise regulations in your area, the Borla exhaust can be quite loud, making it less ideal for those who prefer a more subtle exhaust sound.

4. installation complex: Installing an aftermarket exhaust system, such as the Borla 11971, can be a complex process, and it's recommended that you have it installed by a professional to ensure it's done correctly and safely.

5. Potential for Increased Emissions: Aftermarket exhaust systems, particularly those that result in increased power, may lead to increased emissions. This is something to consider if you're concerned about your carbon footprint or live in a region with strict emissions regulations.

The Borla 11971 Crosstrek FT18-FT21 2.5L Flat 4 Exhaust System offers several advantages, including improved performance, better responsiveness, and a distinctive exhaust note. However, it comes with some cons, such as a higher cost, complex installation, drone, and potential for increased emissions. Ultimately, if you're an avid Subaru enthusiast looking for increased power and a unique exhaust note, the Borla exhaust system might be a worthwhile investment. However, if you prioritize a quieter, more subtle exhaust or are concerned about the cost, you may want to explore other options.

If you're looking for improved performance and a more aggressive exhaust note, the Borla 11971 Crosstrek FT18-FT21 2.5L Flat 4 Exhaust System is an excellent choice. However, given its higher cost, complex installation, and potential for increased emissions, it may not be the best fit for all Subaru Crosstrek owners.
