Thermal R&D's engineering team developed this 3-inch catback specifically for the 2021-2025 F-150 SuperCrew 6.5-foot bed with the 2.7L or 3.5L EcoBoost, targeting the two biggest complaints about aftermarket truck exhausts: drone on the highway and a tone that sounds forced rather than earned. True Helmholtz Technology handles the first problem, and 3-inch mandrel-bent T304 stainless steel handles the second.
Drone-free cabin comfort on long drives. True Helmholtz Technology precisely targets and cancels the low-frequency resonance frequencies that cause the cabin buzz you feel on the interstate. The result is an aggressive note when you get into the throttle and a quiet, comfortable interior at cruise, without any packing material that degrades over time.
Built from T304 stainless steel, mandrel-bent to 3 inches. Mandrel bending keeps the tube diameter consistent through every curve, so exhaust gases move through without restriction. T304 stainless resists corrosion through years of road salt, heat cycling, and pressure washing, and it backs that durability with a lifetime warranty.
Bolt-on fitment with no cutting or welding. The system uses factory mounting locations and drops into place without modifications to the truck. Single-exit routing fits the SuperCrew 6.5-foot bed configuration, and tip options include single or dual polished or coated finishes to match the build.
