Stock exhaust systems on the 5.0L Coyote F-150 are tuned for quiet compliance, not character. Thermal R&D's 3-inch catback exhaust for the 2021-2025 F-150 SuperCab 8ft unlocks the Coyote's natural tone through mandrel-bent T304 stainless steel construction and True Helmholtz resonance control, delivering a deep, aggressive note without the droning frequency that makes long-haul driving miserable.
Drone-free by design. Thermal's True Helmholtz Technology targets and cancels the low-frequency tones responsible for cabin drone. The result is an aggressive sound profile under throttle and a comfortable, livable cabin on highway drives, without compromise between the two.
3-inch mandrel-bent T304 stainless steel throughout. Mandrel bending preserves full tube diameter through every curve, eliminating the flow restrictions that crushed bends create. T304 stainless resists corrosion and heat cycling over the life of the truck, and the system backs that durability with a lifetime warranty.
Bolt-on fitment at factory mounting locations. The system uses the OEM hangers and attachment points on the SuperCab 8ft platform. No cutting, welding, or modification to existing hardware is required. Tips are available in polished or coated finish to match the truck's exterior treatment.
Savage Edition for more aggressive character. Owners who want a stronger exhaust presence can opt for the Savage Edition, which features a shorter muffler design that allows more of the Coyote's natural tone through. The Savage Edition delivers a deeper, more pronounced sound at idle and under throttle while remaining daily-drivable.
