This 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 in. round black chrome on T-304 stainless steel tips on each muffler assembly. Using Borla Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. 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. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
