Borla S-Type Cat-Back Exhaust Systems
Borla’s S-Type Cat-Back Exhaust System 140745BC is designed for 2018-22 Ford Mustang GT 5.0L V8 automatic/manual transmission RWD 2-door models WITHOUT Active Valve Exhaust. NOT recommended for convertibles. This 3 in. diameter system contains a merge X-Pipe for increased performance and improved sound—plus T-304 stainless steel tips with a black chrome finish. (Using Borla Stainless Steel Polish P/N 21461 is NOT recommended with these black chrome tips. Borla suggests cleaning the tips with hot water and a microfiber cloth.)
Borla cat-back and axle-back exhaust systems blend patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium T-304 stainless steel to deliver the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power; and precision computer-controlled CNC manufacturing facilitates an accurate fit. Best of all, Borla stands behind every system—just what you'd expect from the world's most experienced (and most winning) exhaust brand.
