aFe's Twisted Steel headers outflow and outperform the Ford diesel factory exhaust manifolds for a true, bolt-on performance header system. These precision-designed, hand-crafted headers are mandrel-bent from 1-3/4 Inch into 2 Inch heavy duty gauge.120 Inch wall, brushed finish 304 stainless steel tubing and are 100 percent hand Tig-welded for strength and durability. Optimized tube lengths deliver true pulse control technology for improved flow and performance across the power band.

Laser-cut, heavy duty head flanges are machined to match the exhaust ports for a secure seal. Egt ports with plugs, quality hardware and gaskets are included to ensure hassle-free installation and quality fit. Performance Gains: Outflows factory manifolds by up to 7 percent.

Brushed Finish 304 Stainless Steel Construction: Constructed of brushed finish.120 Inch wall, 1-3/4 Inch into 2 Inch mandrel-bent 304 stainless steel tubing for strength and durability. Optimized Tube Lengths: Tube lengths and mitered collectors are optimized for true pulse control technology which improves flow and performance across the power band. Heavy Duty Flanges: These headers incorporate laser-cut, heavy duty flanges machined to match the exhaust ports for a direct-bolt on, leak-free seal.

Egt Ports: Two 1/8 Inch Npt exhaust gas temperature (Egt) ports are incorporated. This allows for easy installation of sensors, gauges or testing equipment. Tig-Welded: 100 percent Tig-welded for strength and durability.

All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
