Product Details

The Borla 140571 S-Type Cat-Back Exhaust System delivers increased horsepower and a more aggressive exhaust note through Borla's patented straight-through and multi-core technology. This complete cat-back system features a 3.5-inch inlet into the muffler with dual 2.25-inch outlets in a split rear exit configuration, optimized to unleash hidden power while improving exhaust velocity and fuel economy.

Key Features:

  • Patented straight-through and multi-core technology for maximum flow
  • Premium 300-series austenitic stainless steel construction for superior durability
  • Ultra-smooth mandrel-bent tubing ensures unrestricted exhaust flow
  • Precision CNC manufacturing for accurate, direct-fit installation
  • Includes connecting pipes, muffler, hardware, and 4-inch round x 14-inch long single rolled angle-cut tip
  • Distinctive S-Type sound level - more aggressive than stock, refined for enthusiasts
  • Backed by Borla's Million-Mile Warranty

Each Borla exhaust system is engineered and tuned on a vehicle-specific basis, with carefully calibrated inner core designs and sound-absorbing composite filament to achieve the ideal balance of performance and sound. The 300-series stainless steel construction resists corrosion far better than inferior 400-series materials, ensuring this exhaust system will deliver peak performance for the life of your vehicle.

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.
