Borla 140915 Cat-Back Exhaust System S-Type 3.5in with Turndown Tips

The Borla 140915 Cat-Back Exhaust System is engineered specifically for 2022-2023 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X models equipped with the 6.2L V8 engine. This performance exhaust system features a 3.5-inch diameter main pipe with dual 2.75-inch turndown tailpipes, delivering an aggressive S-Type sound level that's quieter than ATAK but more assertive than Touring.

Key Features:

• Polyphonic Harmonizer Technology: Patented design uses pipes of different diameters and lengths to create harmonized exhaust notes with a clean, rich, full-bodied sound and zero drone
• S-Type Sound Level: Achieved by replacing the Polyphonic Harmonizer behind the muffler with Borla muffler #60679, providing an aggressive tone without excessive volume
• Straight-Through Multi-Core Design: Patented technology unleashes hidden horsepower and increases exhaust velocity for improved power, throttle response, and fuel economy
• Premium T-304 Stainless Steel: Superior austenitic stainless steel construction resists corrosion far better than T-400 series alternatives like 409 stainless
• Mandrel-Bent Tubing: Ultra-smooth bends maximize exhaust flow and minimize backpressure for optimal performance gains
• Precision CNC Manufacturing: Computer-controlled fabrication ensures accurate fitment and professional installation
• Turndown Tips: Dual 2.75-inch turndown exits provide a clean, functional appearance
