Huge Power Gains and an Aggressive New Exhaust Note
Brutal sound and power is what our good friends over at Kooks are all about, and getting in on that action with your 2009 to 2010 F150 or SVT 5.4L means investing in a pair of Kooks awesome and high-quality long tube headers. These stainless steel headers provide your 5.4L truck with a huge boost in horsepower and torque along with an utterly vicious roar that will have your powerful truck flying down the street or the trail. Kooks' F150 long tube headers are a huge improvement over your truck's factory manifolds and free up a ton of back pressure and restrictions to pave the way more big horsepower and torque when paired with the proper Kooks Y-pipes and custom tuning. These headers are an excellent choice for anyone putting together a monstrous off-road truck build and wants to maximize their F150's or SVT Raptor's power outputs.
1-5/8" Primaries with 2-1/2" Collectors
This set of long tube headers are made entirely out of 304 stainless steel and are expertly welded together right here in the USA at Kook's headquarters in North Carolina. Each header features 1-5/8" diameter primary tubes that are each mandrel-bent to ensure a smooth outflow of exhaust to keep back pressure and restrictions down to the bare minimum. The primary tubes drop down into 2-1/2" diameter collector assemblies that effectively and efficiently combine the gasses from your engine's cylinders into a single stream and shuttle them down into your mid-pipe to promote exhaust scavenging and maximize your power and performance gains. Kooks includes all necessary installation hardware and instructions.
Additional parts required:these headers require a matching Kooks Y-pipe and F150 5.4L Custom Tuning for proper fitment, operation, and power gains.
