The aFe Large Bore HD 4" cat-back exhaust for 2003–2007 Ford diesel trucks with the 6.0L engine uses mandrel-bent 409 stainless steel tubing and smooth curves to reduce backpressure and improve exhaust flow. OE-style band clamps and bayonet hangers make installation straightforward; the high-flow muffler aims to increase horsepower and torque while lowering EGTs. The system ships without a tip and includes a two-year limited warranty.
