Stock F-150 exhausts are tuned for the broadest possible audience, which means acceptable sound for everyone and satisfying sound for almost no one. Thermal R&D's 3-inch catback for the 2015-2020 F-150 5.0L Coyote SuperCrew 6.5ft changes that equation, delivering an aggressive Coyote tone on demand while staying genuinely comfortable on long highway stretches.
True Helmholtz Technology keeps the cabin quiet at cruise. Rather than relying on packing material or generic muffler tuning, Thermal R&D targets specific low-frequency tones that generate cabin drone and cancels them at the source. The result is a system that sounds aggressive when you push the throttle and stays relaxed when you back off, without the fatigue that plagues most performance exhausts on extended drives.
3-inch mandrel-bent T304 stainless steel throughout. Mandrel bending preserves the full 3-inch diameter through every curve, so exhaust gases never hit a restricted section. T304 stainless resists corrosion across seasons and climates, and the tubing maintains its finish long after lesser systems start showing wear.
Bolt-on installation with no cutting or welding. The system uses factory mounting locations, so no modifications to the truck are required. Both single and dual tip configurations are available, with polished or coated finishes to match the build.
