Built specifically for the 2004-2008 F-150 4.6L and 5.4L with extended cab or crew cab short-bed configurations, the MBRP S5204AL cat-back exhaust replaces the full factory system from the catalytic converters back with a dual split-side exit layout that delivers a deeper exhaust note and reduced backpressure.
Dual split-side exit configuration. Rather than a single rear outlet, the system routes exhaust to split exits on both sides of the truck, giving the F-150 a more aggressive stance and a richer, more symmetrical sound profile at idle and under load.
Cat-back replacement for real gains. Swapping the factory exhaust for the S5204AL frees up exhaust flow from the cats back, improving scavenging through the 4.6L and 5.4L V8 powerplants. The result is a more linear throttle response and a noticeable change in exhaust character across the RPM range.
Broad trim-level compatibility. The S5204AL fits the FX4, FX2, Lariat, King Ranch, STX, XL, XLT, Harley-Davidson Edition, 60th Anniversary Edition, and Limited trims spanning the full 2004-2008 production run, making it a versatile fitment across the generation.
Straightforward bolt-on installation. The system uses existing mounting points and hardware locations, so installation stays within reach of a motivated DIY installer with basic hand tools and a floor jack.
