Stock F-150 exhausts are tuned for maximum inoffensiveness, which means throttle noise gets smothered before it ever reaches your ears. Thermal R&D's 3-inch catback for the 2021-2025 F-150 SuperCrew 6.5ft with the 2.7L or 3.5L EcoBoost changes that equation, delivering a deep, aggressive tone through a drone-free system built entirely from T304 stainless steel right here in the USA.
True Helmholtz Technology keeps the cabin livable. Thermal R&D targets the specific low-frequency resonance that causes highway drone by engineering Helmholtz resonator chambers directly into the system. Those frequencies get canceled at the source, so the exhaust sounds aggressive under throttle and composed at cruise, without the fatigue that plagues lesser systems on long hauls.
3-inch mandrel-bent T304 stainless steel construction. Every bend in the tubing maintains a consistent inside diameter because mandrel bending prevents the kinks and collapses that rob flow in cheaper systems. T304 stainless resists corrosion and heat cycling over the life of the truck, and a lifetime warranty backs every weld and seam.
Dual exit tips in polished or coated finishes. Choose polished stainless for a bright, traditional look or a coated tip for a blacked-out appearance. Both options finish the install cleanly at the rear bumper.
Bolt-on installation, no modifications required. The system uses the factory mounting locations on the SuperCrew 6.5ft body configuration, so no cutting, drilling, or fabrication is needed. It drops in place and clamps up with basic hand tools.
Savage Edition for a more aggressive presence. Thermal R&D offers a Savage Edition variant built around a shorter muffler design that lets more of the EcoBoost's natural tone pass through. The result is a deeper, more pronounced sound at idle and under throttle compared to the standard system, while still retaining everyday drivability.

About Thermal R&D: Thermal R&D specializes in American-made stainless steel exhaust systems for domestic trucks and performance vehicles. Each system is engineered to balance sound quality, flow efficiency, and long-term durability, with a focus on fitment accuracy and real-world drivability rather than peak-dyno numbers.
Note: Fits 2021-2025 2.7L/3.5L EcoBoost SuperCrew 6.5ft bed F-150 only. Does not fit vehicles with Gas Particulate Filters (GPF). Verify fitment by checking your under-hood emissions sticker before ordering.
