Stainless Works offers a 2.5" catback for 2003–2011 Ford Crown Victoria and Mercury Grand Marquis 4.6L 2V that uses dual turbo S-tube mufflers and ships without tailpipes or tips. It connects at the factory flanged break point or to Stainless Works headers with leads. The system produces a smooth factory-like sound with manifolds and a notably more aggressive exhaust note when used with headers.
