Performance Exhaust Upgrade. The Milltek Quad Outlet Resonated Cat‑Back Exhaust System with Polished Tips replaces the stock rear exhaust on 2024–2025 Ford Mustang EcoBoost fastbacks equipped with active exhaust. It enhances throttle response, improves exhaust flow, and offers a deeper yet refined exhaust tone thanks to its resonated design. This system is important for enthusiasts seeking both aggressive sound and daily‑drivable refinement.
Construction and Appearance. Fabricated from T304L aircraft‑grade stainless steel, the Quad Outlet Resonated Cat‑Back Exhaust System is mandrel‑bent for optimal flow and minimal turbulence. The quad GT‑100 polished tips provide a premium aesthetic finish. Every component, from piping to tips, is corrosion-resistant and designed to maintain its appearance under harsh conditions.
Installation. Installation is moderate in difficulty and typically requires the removal of the factory exhaust and reusing the OEM slip‑fit clamps and hangers. Drilling is not required, just clamp and hang using factory points. Professional installation using a lift or jack stands is recommended for safety.
Application. This Milltek Quad Outlet Resonated Cat‑Back Exhaust System with Polished Tips fits 2024 and 2025 Ford Mustang 2.3 EcoBoost Fastback (S650) with Active Exhaust.
