Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2021-2025 F-150 5.0L Coyote in SuperCab 6.5ft and SuperCrew 5.5ft configurations, pairing T304 stainless steel mandrel-bent tubing with True Helmholtz Technology to deliver an aggressive exhaust note that stays completely drone-free on the highway.
True Helmholtz Technology eliminates cabin drone. Most aggressive-sounding exhausts come with a trade-off: a low-frequency resonance that turns every highway mile into a headache. Thermal's True Helmholtz design targets and cancels those specific low-frequency tones at the source, keeping the cabin comfortable on long drives while still delivering a deep, throaty bark when you get on the throttle.
3-inch mandrel-bent T304 stainless steel construction. Mandrel bending maintains full tube diameter through every curve, so exhaust gases travel the entire path without restriction. T304 stainless steel resists corrosion and heat cycling over the life of the truck, and the system is backed by a lifetime warranty.
Bolt-on installation with no modifications required. The system uses factory mounting locations throughout, so no cutting, welding, or fabrication is needed. Choose between polished or coated tips to match your build.
The Savage Edition turns up the volume. For F-150 owners who want more presence without giving up daily drivability, the Savage Edition features a shorter muffler design that lets more of the Coyote's natural tone come through. The result is a deeper, more pronounced sound at idle and under throttle compared to the standard system, with the same drone-free performance thanks to True Helmholtz Technology.
