Take your vehicle to the next level with the Borla ATAK® Cat-Back™ Exhaust System—designed for maximum sound, flow, and reliability. Crafted specifically for models equipped with MDS (Multi-Displacement System) valves, this system includes valve simulators that eliminate the factory MDS valves while maintaining full functionality with the ECU, preventing warning lights or error codes. The 2.75" mandrel-bent system features a Merge X-Pipe, boosting scavenging, torque, and throttle response, while smoothing exhaust flow. Engineered with ATAK® (Acoustically-Tuned Applied Kinetics) technology, this system produces Borla’s most aggressive and high-volume sound profile—perfect for enthusiasts looking for a bold exhaust note with no interior drone during cruising. Built from premium T-304 stainless steel, the system offers exceptional corrosion resistance, durability, and long-lasting performance. Although the exhaust does not include tips, it is designed to integrate seamlessly with the factory bezel and exhaust outlets, or can be paired with optional BORLA® tips.
