Stock F-150 exhaust systems prioritize noise reduction over character, leaving the 2.7L and 3.5L EcoBoost sounding muffled and flat. Thermal R&D's 3-inch catback for the 2015-2020 Regular Cab Short Bed F-150 changes that equation with mandrel-bent T304 stainless steel construction, aggressive tone on demand, and a drone-free cabin on the highway.
True Helmholtz Technology eliminates drone. Thermal R&D targets the specific low-frequency tones that vibrate through the cab on extended highway cruises. The Helmholtz resonator design cancels those frequencies at the source, so you get an aggressive exhaust note under acceleration without the fatigue of constant cabin buzz on longer drives.
3-inch mandrel-bent T304 stainless steel throughout. Mandrel bending maintains consistent tube diameter through every curve, preserving flow that crush-bent tubing sacrifices. T304 stainless resists corrosion through salt, heat cycles, and years of use, and the single-exit configuration keeps a clean, purposeful look under the truck.
Bolt-on fitment with no cutting or welding. The system uses factory mounting locations on the 2015-2020 Regular Cab Short Bed F-150, so installation requires no modification to the vehicle. Polished or coated tip options let you match the finish to the rest of the truck's exterior.
