Borla 140977BC Cat-Back Exhaust System with Black Chrome Tips

The Borla 140977BC is a 2.5-inch diameter True Dual Cat-Back exhaust system engineered specifically for the Infiniti Q50. This premium system delivers the signature Borla S-Type sound—a sporty, deep tone with absolutely no cabin drone—while unlocking hidden horsepower through optimized exhaust flow.

Advanced Technology:

• Merge X-Pipe design eliminates turbulent center intersection for smooth, efficient exhaust flow
• Patented Polyphonic Harmonizer Technology uses pipes of varying diameters and lengths to create harmonized exhaust notes for a clean, rich, full-bodied sound
• Patented straight-through and multi-core technology maximizes exhaust velocity for increased power and fuel economy
• Ultra-smooth mandrel bends ensure maximum flow without restriction

Premium Construction:

• Built from T-304 austenitic stainless steel—far superior to T-400 series materials like 409 stainless
• Each tail pipe features a single 4.5-inch black chrome tip on T-304 stainless steel
• Precision CNC manufacturing ensures accurate, bolt-on fitment
• Backed by Borla's Million-Mile Warranty

Maintenance Note: Clean black chrome tips with hot water and a microfiber cloth only. Do not use Borla Stainless Steel Polish (part #21461) on black chrome finishes.

This system delivers the perfect balance of performance gains, aggressive sound, and refined cabin comfort that Borla is renowned for. Also available with bright chrome or carbon fiber tip options.
