The MagnaFlow BRExhaust direct-fit exhaust kit replaces the exhaust behind the catalytic converter for 2003–2006 Lincoln Navigator 5.4L models and includes the clamps and nuts needed for installation. Its mandrel-bent pipes offer improved exhaust flow over crush-bent alternatives, the bolt-on multi-piece design requires no welding, and the aluminized steel construction carries a two-year warranty.
