ATAK Cat-Back Exhaust System

The Borla 140942 is a 3-inch diameter cat-back exhaust system engineered specifically for the 1.6L engine in the 2023-2026 Toyota GR Corolla. It is compatible with both Manual and Automatic transmissions (2025-2026 Automatic only), and features All Wheel Drive fitment. This system utilizes Borla's patented Polyphonic Harmonizer Technology, which employs pipes of varying diameters and lengths to create harmonizing exhaust notes for a clean, rich, full-bodied sound. The dual mufflers are tuned to deliver the aggressive ATAK sound profile without any unwanted drone. It also includes an active exhaust valve. It features ultra-smooth mandrel bends for maximum flow and power, and precision CNC manufacturing ensures an accurate fit. The system includes four polished T-304 stainless steel tips: two 3.5-inch round center tips and two 4.5-inch round outer tips. Systems with black coated or carbon fiber tips are also available. Borla backs this system with a Million-Mile Warranty.
