aFe POWER Twisted Steel Long Tube Headers are crafted from near-equal-length 1-1/2 inch, 16-gauge 304 stainless steel tubing with robust flanges for a reliable, leak-free seal. Unlike formed collectors that create turbulence and restrict flow, these headers use true merge collectors and optimized tube lengths, enhancing flow and performance through advanced pulse control technology. Fully TIG-welded, the smooth curves and increased diameter minimize restriction, allowing exhaust gases to flow efficiently for boosted performance and durability. Dual high-flow, 300 CPSI metallic catalytic converters maximize flow, delivering impressive low-end torque gains. The kit includes all components for an easy, modification-free installation.
