aFe Power's new "Race Only” Twisted Steel Headers deliver an astounding 9 hp and 12 lbs. x ft. torque while out flowing the factory exhaust manifolds. The headers are constructed of 1-5/8” 16-gauge 409 stainless steel tubing with 3/8” thick CNC Laser cut flanges to ensure a leak-free seal. To eliminate dead space that can cause turbulence and hinder flow that formed s are prone to produce, a mitered merge and optimized tube lengths are used for true pulse control technology improving flow and performance. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. Each header comes with a 200 cell, metallic high flow catalytic converter. All components are supplied for a hassle-free bolt-on and go installation with no modifications necessary.
3-to-1 mitered merge decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.
Optimized Tube Lengths:
Tube lengths are optimized for true pulse control technology which improves flow and performance.
CNC Laser Cut Flanges:
Flanges are CNC laser cut not only to be visually appealing but for a durable, precise fit and leak-free seal.
These headers are constructed of durable CNC mandrel bent, stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
High Flow Catalytic Converters:
Each header comes with 200 CPSI (cell per square inch) metallic high-flow catalytic converters for maximum flow.
This performance header is designed to fit in the stock location no cutting or drilling required making it a true bolt-on and go solution. This kit also includes a gasket set and all necessary mounting hardware for a hassle-free installation.
Combine with aFe's Y-pipe (48-46006) For added performance. Combo part number (48-46001-YC)
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 emit and aFe recommends using a programmer but it is not necessary.
