Description

The Walker Quiet-Flow SS 21539 is an exhaust muffler designed for specific fitment on select Ford F-150 and Lincoln Mark LT models from 2004-2008. This muffler features a durable stainless steel body with an aluminized finish, providing resistance to rust and corrosion. It has a single inlet and outlet, both with 2.5-inch inside diameters and offset pipe connections.

The oval-shaped muffler body measures 9 inches wide by 7 inches high, with a body length of 28 inches and an overall length of 32 inches. As a combination muffler, it aims to balance sound attenuation with exhaust flow performance for regular grade applications.
