aFe Power's new "Race Only" Twisted Steel Headers outflow the factory exhaust manifolds and deliver an additional 12 horsepower and 16 foot pounds of torque. The headers are constructed of near equal length 1.625" 16-gauge 304 stainless steel tubing with 3/8" thick CNC machined flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance.
- Tig-Welded: 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
- Retain Factory Sensors: aFe has designed this system to retain all your factory sensors for a hassle free installation.
- Mitered Collectors: Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.
- CNC Machined Flanges: Flanges are CNC machined not only to be visually appealing but for a precise fit and leak-free seal.
- Brushed 304 SS Construction: These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
- Note: This is a "Race Only" product used solely for competition. Its use is limited to closed-course and open-course racing that is formally sanctioned by a recognized racing organization. Any other use including recreational off-road use could be in violation of local, state and federal laws. A check engine light will emitt and aFe recommends using a programmer but it is not necessary.
