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 or 3.5L EcoBoost, pairing an aggressive exhaust note with a drone-free cabin experience through purpose-built resonance control.
True Helmholtz Technology eliminates drone. Rather than muffling exhaust sound broadly, Thermal R&D's True Helmholtz Technology targets and cancels the specific low-frequency tones responsible for cabin drone. The result is a tone that sounds aggressive under throttle and stays comfortable on highway miles.
3-inch mandrel bent T304 stainless steel construction. Every bend in the system preserves full interior diameter, maintaining consistent flow from the catalytic converter back. T304 stainless resists corrosion and heat cycling across the full range of EcoBoost operating conditions.
Bolt-on fitment with no modifications required. The system uses the factory mounting locations on the Regular Cab Short Bed chassis, so installation stays straightforward without cutting, welding, or fabricating new hangers. Finish options include single or dual polished or coated tips to match the truck's look.
