The Chevy Colorado ZR2 is known for its rugged capability and off-road prowess. One way to enhance its performance is by upgrading the exhaust system. In this article, we will explore the power gains from a $1,200 Borla exhaust system, focusing on sound, performance, and fuel economy.
Understanding the Exhaust System
The exhaust system plays a crucial role in the performance of any vehicle. It is responsible for expelling exhaust gases from the engine and can influence sound, efficiency, and overall power output. The Chevy Colorado ZR2 comes with a factory exhaust that is functional but can be restrictive under certain conditions.
What is the Borla Exhaust System?
Borla is a well-respected brand in the aftermarket exhaust industry, known for producing high-quality and performance-oriented exhaust systems. Their systems are designed to improve exhaust flow, reduce back pressure, and enhance the sound of the vehicle.
Key Features of the Borla Exhaust System
- Stainless steel construction for durability
- Mandrel-bent tubing for smooth exhaust flow
- Performance muffler for improved sound
- Easy installation process
Sound Improvements
One of the most noticeable changes after installing the Borla exhaust system is the sound. The factory exhaust can be quiet and subdued, while the Borla system delivers a more aggressive and sporty tone.
Sound Characteristics
The Borla exhaust system produces a deep, throaty rumble that enhances the driving experience. It is designed to minimize drone at cruising speeds while providing an exhilarating sound during acceleration.
Performance Gains
In addition to sound improvements, the Borla exhaust system offers significant performance gains. By reducing back pressure and improving exhaust flow, the engine can breathe more freely, leading to increased horsepower and torque.

Fuel Economy Considerations
Many drivers are concerned about how an aftermarket exhaust system will impact fuel economy. The Borla exhaust system, while designed for performance, can also lead to improved fuel efficiency in certain driving conditions.
Driving Habits and Fuel Economy
Drivers who adopt a lighter foot on the accelerator may notice better fuel economy due to the improved exhaust flow. However, aggressive driving may negate these benefits. Overall, the Borla exhaust system can help optimize fuel efficiency when driven responsibly.
