Borla ATAK Cat-Back Exhaust System for 2016-2024 Infiniti Q50 (V6) 4.5in Chrome Tips

Fits 2016-2024 Infiniti Q50 models (V6-3.0L / Auto) including Red Sport 400, Luxe, Sport, and Sensory trims.

The Borla 140978 ATAK Cat-Back exhaust system is engineered to provide an aggressive, high-performance exhaust note for the Infiniti Q50 without introducing cabin drone. This 2.5-inch True Dual system features Borla's patented Polyphonic Harmonizer technology, which uses varying pipe lengths and diameters to create a rich, multi-layered sound profile. The front muffler includes an internal H-pipe to balance pressure, while the rear section utilizes SwitchFire technology to eliminate turbulent center intersections and blend combustion pulses for improved flow and performance.

Constructed from premium T-304 austenitic stainless steel, this system is built to resist corrosion and maintain its finish far longer than inferior T-400 series alternatives. Mandrel-bent tubing ensures maximum exhaust velocity, while the dual 4.5-inch bright chrome tips provide a substantial aesthetic upgrade. This system is a direct bolt-on installation, manufactured with precision CNC machining for a perfect factory-style fit.
