2020–2026 Ford Explorer ST 3" Front Pipe Back Exhaust System — Black Coated
Upgrade your Ford Explorer ST with a full 3" front pipe back exhaust system engineered for maximum flow, a deeper exhaust tone, and true everyday drivability — from the catalytic converters all the way to the tips.
Unlike a traditional catback, this system runs 3" tubing from the front pipes back, giving the Explorer ST's turbocharged 3.0L EcoBoost engine a more aggressive sound profile and a measurable improvement in exhaust flow. Under acceleration, the tone is deep and throaty. At cruise, it stays refined and comfortable — exactly what True Helmholtz Technology is built to deliver.
At the core of the system is our True Helmholtz Technology, a proprietary resonance-tuning design that targets and smooths out the low-frequency exhaust frequencies that cause cabin fatigue on long drives. The result is a sound profile that feels intentional — commanding under throttle, relaxed when you're not pushing it.
Constructed from mandrel-bent T304 stainless steel throughout, this Explorer ST exhaust system is built for long-term durability and corrosion resistance. The tubing features a mill finish, the front muffler carries a matching mill finish, and the rear Helmholtz chambers are finished in brushed stainless for a premium look under the vehicle.
The system connects directly to the OEM catalytic converters and downpipes, mounts using factory hanger locations, and is designed to fit the OEM rear valance with no cutting or welding required. Emissions are not affected — the front pipes install after the factory catalytic converters.
Finished in an aggressive black coating, the dual 4" angle cut tips add a stealthy, blacked-out look that complements any Explorer ST build. Also available in polished stainless and carbon fiber tip finishes.

⚠️ Heads up for 2026 Ford Explorer ST owners: Some 2026 model year Explorer ST vehicles may be equipped with a Gasoline Particulate Filter (GPF) depending on trim level and production market. Installing this exhaust on a GPF-equipped vehicle may trigger a Check Engine Light.
Does my 2026 Explorer ST have a GPF?
The easiest way to check is your VIN or the Vehicle Emissions Control sticker located under the hood. If GPF is listed, this system is not compatible with your vehicle.
