Construction & Design

The Borla S-Type Cat-Back Exhaust System is crafted from high-grade T-304 stainless steel, which outperforms common T-400 series materials by offering enhanced resistance to rust and corrosion. This ensures the system maintains its structural integrity and appearance over time, even under harsh driving conditions.

Each pipe features mandrel bends that preserve the internal diameter throughout curves, minimizing turbulence and maximizing exhaust flow. The system’s components are precisely engineered using computer numerical control (CNC) technology, guaranteeing a perfect fit and seamless integration with your vehicle’s existing exhaust layout.

Performance & Sound

The system’s merge X-Pipe design improves exhaust gas scavenging, which helps increase horsepower and torque output. This results in a more responsive throttle and enhanced engine efficiency. The signature ATAK® sound delivers a deep, aggressive exhaust note that intensifies with engine RPM, providing an exhilarating driving experience without excessive drone during cruising.
