Get more enjoyment from your 5.0 F-150
Bring a matched Kooks front exhaust upgrade to your Coyote-powered F-150. These kits combine long tube headers with a Y-pipe to the OEM rear exhaust, offering 1-3/4" GREEN, 1-7/8" Performance and 1-7/8" GREEN configurations for the 2015-2020 truck.
SKUs: 1361H230, 1361H420, 1361H430
Choose the package for your engine
The 1-3/4" and 1-7/8" headers both use 3" collectors. Choose the primary around your engine setup, then choose the catalyst for your intended use. Performance cats suit naturally aspirated builds; GREEN is the option here that supports forced induction.
A front upgrade that keeps the rear system
The matching Y-pipe joins the OEM rear interface, letting you retain a compatible cat-back. Buying the headers and front pipework as a kit makes the conversion easier to plan, with the actual combinations and part numbers kept together in the comparison.

Fitting your exhaust
On 2018-on F-150s, the driver-side motor-mount heat shield should be removed or modified to give the header primaries enough clearance.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
