Stock F-150 exhausts prioritize noise suppression over character, leaving the 5.0L Coyote sounding muffled and flat. Thermal R&D's 3-inch catback exhaust for the 2015-2020 F-150 Regular Cab Long Bed unlocks the Coyote's natural tone while staying livable on every commute, highway cruise, and job-site run.

3-inch mandrel-bent T304 stainless steel construction. Every bend in the system maintains full tube diameter, so exhaust gases flow without restriction. T304 stainless resists corrosion through seasonal road salt, mud, and heat cycling, and the system is backed by a lifetime warranty.

True Helmholtz Technology keeps drone out of the cabin. Thermal R&D engineered a resonance-canceling chamber geometry that targets the specific low-frequency tones responsible for cabin drone. The result is an aggressive exhaust note under throttle and a composed, quiet ride at highway cruise, with no buzz at any RPM range.

Dual exit with polished or coated tip options. Both finish choices bolt directly to the factory mounting locations with no cutting, welding, or modification required. The dual exit layout suits the Regular Cab Long Bed configuration cleanly without clearance issues.

The Savage Edition raises the volume without sacrificing daily drivability. A shorter muffler design allows more of the Coyote's natural tone to pass through, producing a deeper, more pronounced sound at idle and under throttle. Drivers who want a stronger overall presence without crossing into drone territory will find the Savage Edition hits that mark.
