Maximum Flow, Full Emissions Compliance: Long Tube Power Without the Compromise
The Kooks 1-7/8" long tube headers with high-flow green catted connection pipes deliver the highest flowing design available for the Raptor R's supercharged 5.2L Predator V8. Hand-built from 304 stainless steel with merged collectors and 200-cell metallic green catalysts, this system provides massive mid-range torque gains, reduced backpressure, and a deeper supercharged growl while maintaining street legality in most states through CARB-compliant high-flow cats.

Frequently Asked Questions
- Q: Will this throw a check engine light?
- A: Possible rear O2 CEL without tune most owners use custom tune to resolve.
- Q: Is a tune required?
- A: Not required for operation but strongly recommended for full power gains and drivability.
- Q: Does it clear the factory supercharger?
- A: Yes, engineered specifically for Raptor R 5.2L supercharged layout.
-
Q: Do these Kooks headers require a tune after installation?
A: Yes. A professional tune is strongly recommended after installing long tube headers. The significant improvement in exhaust flow changes air fuel ratios and requires ECM recalibration to achieve optimal power output and safe operation. -
Q: Will Kooks headers void my factory powertrain warranty?
A: Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part unless they prove the component directly caused the failure in question. Consult your dealer for specifics.

Headers & Manifolds
Performance headers and exhaust manifolds are among the most effective bolt-on upgrades for improving exhaust scavenging, increasing horsepower, and giving your engine a more aggressive exhaust note. Whether you're building a street machine, a track car, or a diesel work truck, the right header or manifold set unlocks real performance gains across the RPM range. Popular Upgrades Top-selling header and manifold products include long-tube headers from BBK and Kooks for V8 muscle cars and trucks, stainless steel shorty headers from Stainless Works for tight engine bay fitments, high-flow cast iron exhaust manifolds for diesel platforms from BD Diesel and ATS Diesel, and turbo manifolds from aFe Power and Invidia for forced-induction builds requiring optimized turbo positioning. What is the difference between long-tube and shorty headers? Long-tube headers route exhaust primaries farther down the chassis before merging at a collector, which improves mid-range and top-end power but requi...
