Thermal R&D's engineering team developed this 3-inch catback exhaust specifically for the 2015-2020 F-150 SuperCab 8-foot bed with the 2.7L or 3.5L EcoBoost, building a system that delivers a deeper, more aggressive tone without the highway drone that makes most aftermarket exhausts unbearable on long hauls.
True Helmholtz Technology keeps the cabin livable. Rather than relying on a generic muffler to muffle everything equally, Thermal's True Helmholtz design targets and cancels the specific low-frequency tones responsible for cabin drone. The result is an exhaust that sounds purposeful at wide-open throttle and stays quiet enough on the interstate that you can hold a conversation.
Mandrel-bent T304 stainless steel throughout. Every bend in the 3-inch tubing is mandrel-formed to maintain full diameter and consistent flow. T304 stainless resists the corrosion, heat cycling, and road salt exposure that eat through mild-steel and aluminized systems over time. A lifetime warranty backs the construction.
Bolt-on fitment at the factory mounting locations. No cutting, no welding, and no modifications to existing hangers or brackets. The system is engineered to the exact dimensions of the SuperCab 8-foot bed configuration, and dual-exit tips finish in either polished or coated to match the truck's look.
The Savage Edition raises the aggression. For owners who want more presence, the Savage Edition swaps in a shorter muffler design that lets more of the EcoBoost's natural tone come through. The sound at idle and under throttle is deeper and more pronounced compared to the standard system, while True Helmholtz Technology still keeps drone in check for daily use.
