The pipe measures 10.75 inches in length and is built from steel with an aluminized finish to help withstand exhaust system heat and road exposure. Its 2.625-inch inlet and 2.25-inch outlet dimensions, along with the 2-bolt loose flange with spherical flare inlet, support proper connection to the existing exhaust layout.

  • Supports service replacement on Ford Explorer and Mercury Mountaineer exhaust systems

Installation Notes and Tips

Verify the vehicle configuration before ordering, especially for 2002-2003 Ford Explorer models without the Sport Package. If the exhaust system uses a welded assembly, replace all required related parts to complete the repair. Confirm inlet and outlet dimensions, flange style, and pipe routing against the original part before installation.

Quality Assurance

Walker manufactures this premium pipe with precision benders and fixture checks to help ensure accurate fitment and straightforward installation. The aluminized steel construction is selected for durability in exhaust service.
