Stock F-150 exhausts leave a significant amount of the 5.0L Coyote's character trapped behind small-diameter tubing and an overly muffled tone. Thermal R&D's 3-inch catback exhaust for the 2021-2025 F-150 SuperCrew 6.5ft unlocks that sound with mandrel-bent T304 stainless steel construction, a drone-free cabin, and a bolt-on fit that requires zero modifications to factory mounting locations.
True Helmholtz Technology keeps the cabin livable. Resonance control is built into the system's architecture, targeting and canceling the low-frequency tones responsible for highway drone. Long-haul drives stay comfortable while the exhaust still delivers an aggressive tone under hard acceleration.
3-inch mandrel-bent T304 stainless steel throughout. Mandrel bending preserves full tube diameter through every bend, so exhaust gases flow without restriction. T304 stainless resists corrosion and heat cycles over the lifetime of the truck, backed by Thermal R&D's lifetime warranty.
Dual exit tips in polished or coated finish. The dual-exit configuration suits the SuperCrew 6.5ft bed profile, and buyers can choose between a polished tip for a clean show look or a coated tip for a blacked-out, understated appearance.
The Savage Edition turns up the presence. For owners who want more aggression without sacrificing daily drivability, the Savage Edition replaces the standard muffler with a shorter design that lets more of the Coyote's natural tone through. The result is a deeper, more pronounced note at idle and under throttle, with a stronger overall presence compared to the standard system, still drone-free thanks to the same Helmholtz architecture.
