Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2015-2020 F-150 Regular Cab Long Bed with the 2.7L or 3.5L EcoBoost, solving the two problems that plague most aftermarket exhausts: cabin drone on the highway and a tone that sounds forced rather than natural. The result is a dual-exit system that delivers a deep, aggressive note without turning a daily driver into an endurance test.
True Helmholtz Technology eliminates drone at the source. Rather than tuning around low-frequency resonance, Thermal's True Helmholtz design targets and cancels the specific tones that cause cabin drone, keeping the interior comfortable on long highway stretches while still producing a strong, aggressive character under throttle when you push the EcoBoost.
3-inch mandrel-bent T304 stainless steel tubing preserves flow. Mandrel bending maintains full tube diameter through every curve, so exhaust gases move without restriction from start to finish. T304 stainless construction handles heat cycles and corrosion over the long term, backed by a lifetime warranty from Thermal R&D.
Bolt-on fitment with no modifications required. The system uses factory mounting locations throughout, so installation does not require cutting, welding, or fabricating new hangers. Polished or coated tip options let you match the finish to the truck's exterior.
Savage Edition available for more presence. The Savage Edition swaps in a shorter muffler design that allows more of the EcoBoost's natural tone through the system. The character at idle and under throttle becomes deeper and more pronounced compared to the standard system, while True Helmholtz Technology keeps the drone-free performance intact for daily driving.
