Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2021-2025 F-150 Regular Cab Short Bed with the 2.7L and 3.5L EcoBoost, building a system that delivers a genuine performance exhaust note without the highway drone that makes most aftermarket setups unbearable on longer hauls.
True Helmholtz Technology keeps the cabin livable. Rather than relying on packing material or generic resonators, Thermal R&D uses a precision-tuned Helmholtz chamber design that targets and cancels the specific low-frequency tones responsible for cabin drone. The result is an aggressive sound under throttle that settles into a comfortable, refined tone on the highway.
3-inch mandrel-bent T304 stainless steel construction. Every bend in the system maintains full tube diameter with no crimping or restriction, and T304 stainless steel resists corrosion through years of road salt, heat cycles, and daily use. Polished or coated tip options let owners tailor the finished look to their truck.
Bolt-on installation with no modifications required. The system uses factory mounting locations throughout, so no cutting, welding, or fabrication is needed. A straightforward swap onto the existing hangers means installation stays within reach for a capable DIY installer.
The Savage Edition raises the volume. For owners who want a stronger presence, the Savage Edition swaps in a shorter muffler design that lets more of the EcoBoost's natural tone come through. The idle note is deeper and more pronounced, throttle response is louder and more immediate, and the overall character is more aggressive, all while keeping daily drivability intact.
