S-Type Cat-Back Exhaust System

The Borla S-Type Cat-Back Exhaust System (Part #140702) is engineered specifically for the 2016-2018 Ford Focus RS equipped with the 2.3L 4-cylinder turbocharged manual transmission and all-wheel drive. Constructed from premium T-304 austenitic stainless steel, this system is designed for maximum performance and long-term durability. Borla's patented straight-through and multi-core technology aims to increase exhaust velocity, which can lead to gains in horsepower, driving excitement, and fuel economy, all while delivering the distinctive Borla Sound of Power. The system features ultra-smooth mandrel bends for optimal flow and precision CNC manufacturing for an accurate fit. It replaces the factory exhaust from the service-point back, utilizing original vehicle hangars and isolators for installation. This particular S-Type system includes a "Sound Suppressing Valve" simulator, which eliminates the factory valve to ensure maximum flow and prevent warning lights. The exhaust system terminates in a single split rear exit with 4-inch bright chrome on T-304 stainless steel rolled angle-cut tips. The pipe diameter measures 3 inches leading into the muffler and 2.25 inches exiting the muffler. Borla backs this system with a Million-Mile Warranty.
