The Borla S-Type axle-back exhaust system is a 2.5 inch diameter design built for the 2024-2025 Ford Mustang EcoBoost 2.3L that is not equipped with Active Exhaust. It delivers the classic S-Type sound level with no drone inside the vehicle and finishes with a single 4 inch round black chrome T-304 stainless steel tip on each muffler assembly. Borla recommends cleaning the black chrome tips with hot water and a microfiber cloth rather than stainless steel polish. Borla cat-back and axle-back systems use patented straight-through, multi-core technology with ultra-smooth mandrel bends and CNC manufacturing for increased exhaust velocity, added power, and an accurate bolt-on fit. Built from premium all-welded T-304 stainless steel, superior to T-400 series materials such as 409, this axle-back mounts behind the factory catalytic converters and is 50-state emissions legal. Every Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.
