Detailed Description

The AP Exhaust 700458 muffler is engineered as a direct-fit replacement for vehicles in the Ford Escape, Mazda Tribute, and Mercury Mariner platform family.

It is a practical choice for replacing a worn or damaged factory muffler on the specified vehicles while maintaining the original exhaust configuration.

What It Helps Address

• Exhaust noise from a worn or damaged muffler
• Rust-related muffler replacement on aluminized steel systems
• Factory-style exhaust fitment on listed Ford Escape, Mazda Tribute, and Mercury Mariner models
• Incorrect muffler routing caused by mismatched inlet and outlet locations
• Restoring OE comparable exhaust sound after muffler failure

Installation Notes

Verify inlet and outlet orientation before installation: this muffler uses a 2.25-inch center inlet and a 2-inch right center outlet with a flange outlet type.
