We’re excited to announce the official release of the STILLEN Cat-Back Exhaust System for the 2021–2025 Ford F-150. Whether you’re hitting the trails, towing heavy loads, or just want a more aggressive tone on your daily drive, STILLEN’s newest exhaust delivers performance, sound, and style—all without the drone.

Built to Perform. Built to Last.
Each system is crafted from 409 stainless steel, offering exceptional durability and corrosion resistance. Made right here in the USA and backed by a limited lifetime warranty, these exhausts are engineered for real truck owners who demand both quality and functionality.
Three Options to Match Your Build:
- Polished Tip – Classic shine and a clean look with a refined, sporty tone.
- Black Tip – Stealthy styling with the same premium performance.
- Off-Road Series – Designed for serious adventurers. This version removes the rear section to improve departure angles and reduce the risk of damage during extreme off-road use. It also delivers the most aggressive exhaust note of the lineup.
Drone-Free, Engine-Specific Tuning
We know how important sound quality is. STILLEN’s Cat-Back system is carefully tuned to provide a deep, sporty tone without the cabin drone, no matter which engine you’re running—2.7L EcoBoost, 3.5L EcoBoost, or 5.0L V8.
