2.5-Inch Cat-Back Exhaust System

The Stainless Works catback exhaust is a 2.5-inch diameter performance system constructed from 304 stainless steel, engineered to replace restrictive factory exhaust components on 2003-2011 Ford Crown Victoria and Mercury Grand Marquis models equipped with the 4.6L 2V engine. This system utilizes dual turbo-chambered mufflers and includes an X-pipe crossover for optimized exhaust scavenging and a distinct performance sound. The exit features dual 3.5-inch polished, single-wall, slash-cut tips that provide a clean, finished appearance. This configuration allows for a direct fitment to the stock exhaust manifolds or compatibility with Stainless Works headers when used with matching leads. The assembly is built to withstand demanding conditions and is backed by a limited lifetime warranty. Installation requires basic hand tools for standard catback replacement; however, as this is a performance-oriented upgrade, ensuring proper alignment of the X-pipe and tailpipes is recommended to maintain factory-style clearance.
