Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2015-2020 F-150 Regular Cab Short Bed with the 2.7L or 3.5L EcoBoost, pairing mandrel-bent T304 stainless steel construction with True Helmholtz Technology to deliver a deep, aggressive tone without the low-frequency drone that ruins long highway drives.
True Helmholtz Technology keeps the cabin livable. Rather than simply reducing overall volume, Thermal's proprietary resonance-canceling design targets and eliminates the specific low-frequency tones responsible for cabin drone. The result is an exhaust that sounds aggressive under throttle and settles into a composed, deep note at cruise, without fatiguing the driver on longer runs.
T304 stainless steel, mandrel bent to 3 inches. Every bend in the system is mandrel formed to maintain a full 3-inch diameter through each curve, keeping exhaust flow consistent from the catalytic converters to the dual-exit tips. T304 stainless steel resists corrosion and heat cycling across the full service life of the truck, backed by a lifetime warranty.
Bolt-on fitment at factory mounting points. The system uses OEM mounting locations and requires no cutting, welding, or modifications to the truck. Tips are available in polished or coated finish to match the truck's style.
The Savage Edition raises the intensity. For drivers who want more presence without sacrificing daily drivability, the Savage Edition replaces the standard muffler with a shorter design that lets more of the EcoBoost's natural tone come through. The sound is deeper and more pronounced at idle and under throttle, with a stronger overall character compared to the standard system, while True Helmholtz Technology still manages resonance for a drone-free cabin.
