Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2021-2025 F-150 SuperCab 8-foot bed with the 2.7L and 3.5L EcoBoost, building a system around mandrel-bent T304 stainless steel that flows freely, sounds aggressive, and stays drone-free on the highway.
True Helmholtz Technology keeps the cabin quiet. Low-frequency resonance is the enemy of any daily-driven performance exhaust. Thermal's True Helmholtz Technology targets and cancels those specific tones at the source, so the truck stays comfortable on long drives while still delivering a deep, pronounced note when the throttle opens up.
3-inch mandrel-bent T304 stainless tubing flows without restriction. Mandrel bending maintains full tube diameter through every curve, eliminating the collapsed bends that choke exhaust flow in stamped OEM systems. T304 stainless steel construction resists corrosion across every season and climate, and the system is backed by a lifetime warranty.
Dual exit tips finish the build cleanly. Available in polished or coated finish, the tips are sized and positioned to complement the SuperCab 8-foot bed proportions. The system uses all factory mounting locations, so installation is a bolt-on with no cutting, welding, or fabrication required.
The Savage Edition turns up the intensity. For owners who want more presence without sacrificing daily drivability, the Savage Edition swaps in a shorter muffler design that lets more of the EcoBoost's natural tone come through. The result is a deeper, more aggressive note at idle and under throttle compared to the standard system, while True Helmholtz Technology still keeps drone in check on the highway.
