Milltek's Cat-Back for the Ford F-150 SuperCrew 5.0 V8 (2021 and later, including Tremor) is a 3-inch (76.2mm) T304L stainless steel exhaust that gives the Coyote V8 a deeper, stronger tone and improved flow, at direct OEM fitment. It is built for F-150 owners who want their truck to sound like the V8 it is, with a hand-finished stainless system that bolts to the factory hangers. No cutting or welding.
What is the Milltek cat-back for the F-150 SuperCrew?
It is a full cat-back replacement in hand-finished T304L stainless, mandrel-bent in 3-inch (76.2mm) pipe. It ships in two characters: the Road+ version is tuned for a fuller tone with cruise manners kept in check, and the Race version is the louder, more aggressive option. Tremor-specific variants suit that model's rear exit.
Who is it for?
It suits the 5.0 V8 SuperCrew and Tremor owner who wants a real V8 note for daily driving, towing and weekends. Choose Road+ if you cover long highway miles and want tone without fatigue, or Race if maximum volume is the priority.
What does it include and what are the specs?
The system ships as a complete cat-back with your chosen tip finish, OEM-compatible hangers and the fixings for a bolt-on fit.

What are the limitations, and who is it NOT for?
This is a cat-back for the SuperCrew (5.5ft bed) 5.0 V8, so confirm your cab and bed before ordering. It does not replace the catalytic converters, and on a cat-back alone expect a modest power change rather than a headline dyno figure. The Race version is loud by design; pick Road+ if you want a calmer highway cruise.
Every system is built in hand-finished T304L stainless. (Source: Milltek Sport, About Us.)
