Detailed Product Features and Specifications
The Walker Quiet-Flow SS 21387 muffler features a robust stainless steel body that resists rust and extends service life. Its aluminized finish further protects against corrosion from road elements. The muffler’s oval shape and specific dimensions—9.75 inches wide, 4.25 inches high, and 19 inches in body length—ensure a proper fit within the exhaust system of compatible vehicles. The inlet and outlet pipe connections are offset, with the inlet offset measuring 2.875 inches, facilitating installation in the exhaust layout of Ford Taurus and Mercury Sable models. The inlet inside diameter is 2.25 inches, while the outlet outside diameter is 2.5 inches, matching factory exhaust pipe sizes for a secure connection. This combination muffler type includes one inlet and one outlet, designed for specific fitment rather than universal application.
