2016-2024 Infiniti Q50 Cat-Back Exhaust System S-Type Part # 140977CFBA

This 2.5" diameter True Dual BORLA® Cat-Back™ system was designed specifically for the Q50. It features a merge X-Pipe and Borla's patented Polyphonic Harmonizer technology for increased performance and improved sound. BORLA®'S Polyphonic Harmonizer Technology utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. Completely eliminating the turbulent center intersection of a standard X-Pipe, BORLA®'S patented SwitchFire™ design truly blends the combustion pulses from both sides of the engine for improved performance and a custom sound. The classic S-Type sound level delivers a sporty sound and a deeper tone without any drone inside the cabin. The system has a single 4.5" carbon fiber with black anodized center tip on each tail pipe. Systems with bright chrome On T-304 stainless steel tips, and black chrome on T-304 stainless steel tips are also available.

BORLA® Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere.

Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum a flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.

Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you‘d expect from the world‘s most experienced (and most winning) exhaust brand.
