Make your F-150 sound like the V8 it is
For a competition build that puts the Coyote engine first, these Kooks long tube headers give your 2021-2026 F-150 a matched starting point for its performance exhaust. Choose 1-3/4" or 1-7/8" primaries, then pair them with the correct Kooks Y-pipe to suit the rest of the truck and the catalyst specification you want.
SKUs: 13712200, 13712400
Choose the primary for your engine
Both primary options feed 3" collectors. Primary size should reflect your engine output, induction and intended use. We can help you choose the header and Y-pipe combination for your current build, including any further engine upgrades you have planned.
The essential header hardware is included
Multi-layer gaskets, header bolts, ball-and-socket hardware and the O2 extension kit are included. Add the matching 13713-series Kooks Y-pipe to connect the headers to your rear exhaust. Choose its catalyst option for your engine and intended use.
Allow for the engine-mount heat shield
On these 2021-2026 trucks, fitting the long tube headers can require removal or modification of the driver-side engine-mount heat shield for primary-tube clearance. We recommend professional fitting, careful routing of the O2 wiring and calibration for the completed exhaust, followed by a first heat-cycle fastener check.
Tuning for your header upgrade
We recommend a tune with these headers, matched to your engine and the completed exhaust. Talk to us about tuning for your vehicle and modifications.

Questions before you order
Frequently asked questions
Can I connect these to the factory Y-pipe?
Use the matching Kooks Y-pipe for this long tube conversion. It provides the correct connection from the header collectors to the rear exhaust.
Is any modification needed during fitting?
The driver-side engine-mount heat shield may need to be removed or modified for primary-tube clearance. Your installer should check that alongside wiring and exhaust clearances.
Are O2 extensions included?
Yes, together with the gaskets, header bolts and ball-and-socket hardware.
What use are these headers intended for?
Both options are competition, off-road and track-use parts only. Public-road use is excluded, and Kooks requires a competition-use waiver.
