Borla S-Type Axle-Back Exhaust System with Polished Tip (11751) - 2005-2009 Ford Mustang V6
Give your six-shooter the performance presence and muscular voice it deserves with the Borla S-Type Axle-Back Exhaust System. Specially custom-engineered for the 2005 to 2009 Ford Mustang V6 (4.0L), this premium setup is purpose-built for owners who want to upgrade their pony car's style and sound profile. The legendary S-Type configuration unleashes a deep, sporty, and aggressive growl under acceleration, yet settles down completely to a smooth hum while cruising. By flowing an impressive 724 CFM—a massive 346 CFM increase over the restrictive factory layout—this free-flowing exhaust reduces backpressure to unlock solid double-digit horsepower numbers, sharper throttle response, and subsequent mileage improvements.
This high-performance upgrade features 2.5 inch mandrel-bent tubing crafted entirely from aircraft-grade T-304 austenitic stainless steel, making it over 1/3 lighter than the stock rear muffler assembly. This top-tier material offers ultimate protection against rust, corrosion, and structural cracking under everyday driving conditions. Built using precision computer numerical control (CNC) manufacturing, this kit guarantees a perfect, direct bolt-on fitment using standard factory hangers. The system routes down to a clean single right rear exit configuration, crowned with a large 4 inch round, rolled, angle-cut polished stainless steel tip embossed with the iconic Borla logo. Patented straight-through and multi-core technologies eliminate interior cabin drone completely, backed by an industry-leading Million-Mile Warranty.
