Detailed Product Description

AP Exhaust part number 2551 is an exhaust muffler engineered with a 12-inch body length, 11-inch body width, and 5.5-inch body height, with an overall length of 25 inches. The oval muffler body is made from aluminized steel and uses a baffled internal design to maintain an OE-comparable sound level without tunability. Its inlet is positioned at the right center, while the outlet is centered, matching the layout needed for the listed Ford Edge and Lincoln MKX left-side applications. This part cross-references Ford OE number 8T4Z5230A for the same application.

For drivers searching for a Ford Edge muffler replacement or a Lincoln MKX left muffler replacement, AP Exhaust 2551 provides a direct-fit service option for the specified model years. The welded OE system note means related exhaust sections should be inspected closely during replacement.

Common Problems This Muffler Can Address

• Exhaust noise caused by a rusted or leaking muffler body
• Reduced sound control from a damaged internal baffle structure
• Corrosion-related failure in an aluminized steel exhaust section
• Fitment issues when replacing the left-side muffler on a welded OE system
• Exhaust vibration or rattling from a deteriorated muffler assembly

Installation Notes and Tips

Verify inlet and outlet orientation before installation, since this muffler uses a right-center inlet and center outlet configuration. Because the OE system was a welded assembly on the listed Ford Edge and Lincoln MKX applications, inspect adjoining exhaust parts for wear, corrosion, or damage before beginning the repair. Confirm left-side placement and match the 2-inch pipe connections to the existing exhaust layout.

Quality Assurance

AP Exhaust manufactures replacement exhaust components for service applications that require OE-style fit and sound characteristics. Part number 2551 is built to the listed dimensions and configuration for the specified Ford Edge and Lincoln MKX fitments.
