AP Exhaust 2408 Muffler Overview

AP Exhaust 2408 is a baffled oval exhaust muffler built with aluminized steel for service on select dual-exhaust Ford, Lincoln, and Mercury applications. It uses an OE-comparable sound level and a flange outlet layout to support a direct-style replacement on the left side of the exhaust system.

Compatible With 2003-2011 Ford Crown Victoria, left; 2003-2011 Lincoln Town Car, left; and 2003-2011 Mercury Grand Marquis, left. This AP Exhaust 2408 muffler is a fitment-based replacement for vehicles using the Challenge LTW configuration.

Detailed Description

AP Exhaust 2408 is an exhaust muffler for left-side dual-exhaust applications on the 2003-2011 Ford Crown Victoria, 2003-2011 Lincoln Town Car, and 2003-2011 Mercury Grand Marquis. Its oval, baffled construction is sized for a direct replacement approach, while the aluminized steel body helps resist everyday exhaust-system wear. The OE-comparable sound level supports a factory-style exhaust note rather than an aggressive tone.

This part number 2408 is part of AP Exhaust’s Challenge series and uses a right-center inlet with a center flange outlet. For vehicles with welded OE exhaust assemblies, replacement planning should account for the full system layout and the notes listed for each application.

What It Helps Address

  • Rust-through or corrosion in the muffler body
  • Exhaust noise from a damaged internal baffle structure
  • Restricted exhaust flow caused by a failing muffler
  • Factory exhaust tone that no longer matches OE sound levels
  • Replacement needs on left-side dual-exhaust layouts

Installation Notes and Tips

Verify the vehicle’s left-side exhaust configuration, inlet and outlet orientation, and flange connection before installation. This muffler is listed for 2003-2011 Ford Crown Victoria, left; 2003-2011 Lincoln Town Car, left; and 2003-2011 Mercury Grand Marquis, left, with dual exhaust and Challenge LTW notes. Because the OE system was a welded assembly on these applications, related exhaust parts noted in the vehicle listing should be inspected and replaced as needed to complete the repair correctly.

Quality Assurance

AP Exhaust manufactures this muffler as a regular-grade replacement component for the Challenge series. The aluminized steel body, baffled design, and OE-comparable sound level provide a practical service part for restoring exhaust function on the listed applications.
