aFe Power Twisted Steel 1-3/4" Stainless Steel Shorty Headers; 48-33022

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" into 2" heavy duty gauge .120" wall, brushed finish 304 stainless steel tubing and are 100% 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.
\nPerformance Gains: Outflows factory manifolds by up to 7%.
\nBrushed Finish 304 Stainless Steel Construction: Constructed of brushed finish .120" wall, 1-3/4" into 2" mandrel-bent 304 stainless steel tubing for strength and durability.
\nOptimized Tube Lengths: Tube lengths and mitered collectors are optimized for true pulse control technology which improves flow and performance across the power band.
\nHeavy Duty Flanges: These headers incorporate laser-cut, heavy duty flanges machined to match the exhaust ports for a direct-bolt on, leak-free seal.
\nEGT Ports: Two 1/8" NPT exhaust gas temperature (EGT) ports are incorporated. This allows for easy installation of sensors, gauges or testing equipment.
\nTIG-Welded: 100% TIG-welded for strength and durability.
\nAll aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
