Thermal R&D's engineering team developed this catback exhaust specifically to solve the problem most performance exhausts create: a cabin full of low-frequency drone on the highway. The result is a system that sounds aggressive under load but stays livable on long hauls, all wrapped in 3-inch mandrel-bent T304 stainless steel tubing.
True Helmholtz Technology eliminates drone. Rather than relying on generic packing material or a second muffler as a bandage, Thermal R&D targets the specific low-frequency tones responsible for cabin resonance and cancels them at the source. The 2.7L and 3.5L EcoBoost tones that would otherwise vibrate through the floor are addressed without muting the exhaust note you actually want to hear.
Mandrel-bent T304 stainless steel throughout. Every bend in the system maintains full 3-inch diameter from start to finish, keeping exhaust velocity consistent where a crush-bent tube would pinch flow. T304 stainless resists heat cycling and corrosion across the full service life of the truck.
Bolt-on installation with no modifications required. The system uses factory mounting locations on the 2015-2020 F-150 SuperCrew with the 6.5-foot bed, so no cutting, welding, or hanger fabrication is needed. Tip options include single or dual polished or coated finishes, letting the owner match the look to the truck.
