Stock exhaust systems on the 2.7L and 3.5L EcoBoost F-150 leave performance and sound on the table, prioritizing quiet comfort over everything else. Thermal R&D's 3-inch catback exhaust replaces that compromise with mandrel-bent T304 stainless steel tubing and True Helmholtz Technology, delivering an aggressive tone without the low-frequency drone that makes long highway stretches miserable.
True Helmholtz Technology keeps the cabin livable. Rather than masking resonance with packing material or generic baffling, the system targets and cancels specific low-frequency tones at the source. The result is a throaty EcoBoost note under hard acceleration and a calm, drone-free cabin during cruising, no compromise required.
Mandrel-bent T304 stainless steel construction. Every bend in the system is mandrel-formed, preserving the full 3-inch inside diameter through every curve. T304 stainless resists corrosion and heat cycle fatigue across the life of the truck, and the lifetime warranty backs that durability with real coverage.
A bolt-on install that uses factory mounting locations. No cutting, no welding, and no modifications to existing hardware. The system fits SuperCab 6.5-foot and SuperCrew 5.5-foot bed configurations and accommodates both the 2.7L and 3.5L EcoBoost engines. Tips are available in single or dual configuration, finished in either polished or coated stainless to match your build.
