Product Description

The Borla 140730BC ATAK Cat-Back Exhaust System is a high-performance aftermarket exhaust engineered specifically for the 2016-2018 Ford Focus RS equipped with the 2.3 L turbocharged four-cylinder and all-wheel drive. This premium cat-back replaces the factory rear exhaust section with a straight-through design using large-diameter stainless steel tubing and Borla's most aggressive street sound tuning - ATAK®. Its sound suppressing valve simulator eliminates the restrictive stock valve, ensuring unrestricted flow and maximizing exhaust tone and character without triggering warning lights.

Built from premium T-304 stainless steel with precision mandrel bends, the 140730BC enhances exhaust velocity and reduces backpressure compared to the factory system. Polyphonic Harmonizer Technology harmonizes multiple exhaust frequencies into a rich, powerful note appropriate for performance driving, while the black chrome single 4" round rolled angle-cut tip adds a bold visual finish. Designed for direct, bolt-on installation using existing hangers and hardware, this Borla ATAK cat-back exhaust provides dramatic sound and performance improvements for Focus RS owners seeking maximum auditory impact and durable construction backed by one of the longest industry warranties.
