Upgrading to a Borla cat-back exhaust system on your Infiniti G37 is a popular modification among car enthusiasts looking to enhance performance and sound. This article delves into the specifics of how much horsepower you can expect from this upgrade.
Understanding Cat-Back Exhaust Systems
A cat-back exhaust system refers to the section of the exhaust system that runs from the catalytic converter to the rear of the vehicle. Upgrading this part can lead to improved exhaust flow, which often translates into increased horsepower and torque.
Why Choose Borla?
Borla is known for its high-quality exhaust systems that are designed for performance and durability. Here are some reasons why many G37 owners opt for Borla:
- Performance: Borla exhausts are engineered to maximize airflow and minimize back pressure.
- Sound: They provide a deep, aggressive exhaust note that enhances the driving experience.
- Quality: Made from high-quality materials, Borla exhausts are built to last.
Expected Horsepower Gains
When upgrading to a Borla cat-back exhaust on your G37, the expected horsepower gains can vary based on several factors, including the specific model of the exhaust and any additional modifications made to the vehicle.
Typical Gains
Most G37 owners report an increase in horsepower ranging from 5 to 15 HP after installing a Borla cat-back exhaust system. This can be influenced by:
- The model of the Borla exhaust (e.g., S-Type, ATAK).
- Additional performance modifications (e.g., cold air intake, tuning).
