The mufflers feature a black high-temperature paint finish, and the quad tips are crafted from 304 stainless steel with a black ceramic coating, providing a sleek custom appearance with double-wall round tips and angled cut edges.
Installation. Installation is straightforward using factory mounting locations, with all necessary hardware included for a bolt-on fit without cutting or drilling. The system utilizes slip-fit inlet connections and clamp-on inlets for seamless integration.
Warranty. This product is backed by a lifetime limited warranty, ensuring long-term coverage for durability and performance.
Application. Designed for 2024 to 2026 Ford Mustang models equipped with the factory performance/active exhaust option, including both the 5.0-liter V8 GT and 2.3-liter EcoBoost engines, as well as the Dark Horse trim level. Compatible with coupe and convertible body styles. This system includes OEM-style valves but requires reuse of the factory valve actuators to maintain proper operation.
