This 2.5" diameter BORLA Axle-Back system is designed for use on EcoBoost cars WITHOUT the Active Exhaust feature. It features the classic S-Type sound with no drone inside the vehicle and single 4" round carbon fiber with black anodized center tips on each muffler assembly. Systems with bright chrome on T-304 stainless steel tips, and black chrome on T-304 stainless steel are also available. BORLA Cat-Back and Axle-Back exhaust systems feature 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, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
