Comprehensive Review of the Borla 140903 Exhaust System
The Borla 140903 is engineered to provide a significant upgrade over factory exhaust systems. With a focus on performance, sound, and durability, this cat-back exhaust system is made from high-quality T-304 stainless steel, known for its resistance to corrosion and longevity.

This design philosophy is grounded in Borla's extensive experience in motorsports and performance tuning, ensuring that the 140903 meets the demands of serious drivers.
Design and Build Quality
The Borla 140903 is crafted with precision, showcasing a sleek and polished finish that not only enhances the aesthetic appeal of your vehicle but also contributes to its durability. The T-304 stainless steel construction provides excellent resistance to rust and corrosion, which is crucial for longevity, especially in varying climates. The mandrel-bent tubing ensures smooth exhaust flow, reducing turbulence and improving performance. The exhaust tips are typically polished to a mirror finish, adding a touch of sophistication to your vehicle's rear end.
Performance Enhancements
One of the standout features of the Borla 140903 is its ability to improve engine performance. Users can expect a noticeable increase in horsepower and torque, thanks to the system's efficient design that reduces back pressure. During testing, vehicles equipped with the Borla 140903 showed an increase of up to 10-15 horsepower, depending on the make and model. The exhaust note is aggressive yet refined, providing a sporty sound without being overly loud or intrusive during regular driving conditions. This balance makes it an excellent choice for daily drivers who still want a performance edge.
Installation Process
Installing the Borla 140903 is generally straightforward, especially for those with basic mechanical skills. The system is designed as a direct bolt-on replacement for the factory exhaust, which means no cutting or welding is required. Most users report being able to complete the installation in about 1-2 hours using standard hand tools. Borla provides detailed instructions, and the fitment is precise, ensuring a secure and leak-free installation. However, for those who prefer a professional installation, many auto shops are familiar with Borla products and can install the system efficiently.
Sound Profile
The sound profile of the Borla 140903 is one of its most appealing aspects. It produces a deep, aggressive tone that is unmistakable yet refined enough for everyday driving. The system utilizes Borla's patented technology to minimize drone at cruising speeds, making it comfortable for long drives.
