Enhance performance with superior exhaust flow and durability.
The Advanced FLOW Engineering Twisted Steel long tube header is engineered to significantly improve engine performance, delivering an increase of +24 horsepower and +27 pounds per foot of torque compared to factory systems. Constructed from high-grade 304 stainless steel, the header features 1-3/4 inch primary tubes that transition to 2-1/2 inch collector pipes, ensuring optimal exhaust flow and longevity. Each unit is meticulously hand TIG-welded by certified craftsmen, providing proven durability and strength under high-performance conditions.
This exhaust header incorporates a 6-2-1 Tri-Y design, which pairs opposite firing cylinders with equal, specifically tuned primary lengths. This design maximizes scavenging and enhances torque throughout the power band, making it a valuable addition for performance enthusiasts. The high-quality 3/8 inch thick laser-cut flanges ensure a superior seal at the head surface, while the included high-flow catalytic converter promotes maximum exhaust flow.
Installation is straightforward, thanks to the inclusion of high-quality band clamps and hardware, which provide a complete 360-degree sealing surface for a leak-free fit. The polished finish not only enhances the aesthetic appeal but also offers high resistance to corrosion, ensuring that the header maintains its performance and appearance over time. This system is not 50 state legal and is designed for rear exit applications.
