Some 2020–2027 Explorer ST owners want to wake the neighbors. Others just want their 400 horsepower SUV to finally sound like it should. The 2.5" front pipe back exhaust is built for the second group, delivering a deep, refined exhaust note that adds character without overwhelming the cabin.

Also fits 2020–2027 Ford Explorer Platinum models equipped with the 3.0L EcoBoost. The system uses the factory hanger locations and exits through the factory rear valance with no modifications required, making it a true direct bolt-on for both Explorer ST and 3.0L Platinum owners.

It uses the same True Helmholtz Technology, T304 stainless steel construction, and drone-free highway manners found in our larger systems, just dialed back for a smoother daily driving experience.

Like every exhaust we build, this system uses mandrel-bent T304 stainless steel for long-term durability, corrosion resistance, and consistent exhaust flow.

The system mounts directly to the OEM catalytic converters and downpipes, uses factory hanger locations, and fits the OEM rear valance on both the Explorer ST and 3.0L Explorer Platinum with no cutting or welding required.

True Helmholtz Technology uses precision-tuned resonance chambers to target and cancel the low-frequency exhaust tones that cause cabin drone. The result is a system that sounds aggressive under throttle while remaining smooth and comfortable during daily driving and highway cruising.

The dual 4" angle-cut black coated tips deliver a clean, flush fit with a stealthy blacked-out finish.

⚠️ Heads up for 2026+ Explorer ST and Platinum 3.0L owners: Some vehicles may be equipped with a Gasoline Particulate Filter (GPF), depending on production date and market. Installing this exhaust on a GPF-equipped vehicle may trigger a Check Engine Light.

Does my Explorer 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.

Not sure? Contact us before ordering and we'll help you confirm compatibility. We are also actively developing a GPF-compatible Explorer system, so stay tuned for updates.

The ST is Awakened

"Bought the 2. 5 inch system based on internet sound clips and reviews. The sound is perfect - no drone at highway speeds, quiet when cruising, raucous when on it. The Hoover vacuum sound is gone. Fit and finish of the system looks excellent and it fit my ‘25 ST perfectly. Great product at a fair price."

Steven W. (5/5)

Very happy with my purchase

"Very happy with my purchase of this exhaust. The packaging was great, parts fit perfect, and the installation was as straight forward as the video. My ST sounds great, not too loud, just enough to know it’s a performance exhaust."

Brandon B. (5/5)

Quality and sound you can trust

"Recently purchased the 2. 5” w/ black tips for my 2026 Explorer ST. The sound is perfect, and really make the ST a totally different car! Took just over 2 1/2 hrs to install in my driveway. Highly recommend to anyone looking for that exhaust sound!"

Alberto H. (5/5)

The Sound This SUV Should Have Had from the Factory

"The stock exhaust on the Explorer ST is a joke, but the Thermal R&D 2. 5-inch system completely transformed it. I was worried about the V6 sounding 'raspy' or like a clapped-out sedan, but this has a deep, mature rumble. This is the kit if you wanted that signature deep growl without the "trumpet" sound at high RPMs."

Scott A. (5/5)

Thermal 2. 5 exhaust for my 2025 Explorer ST

"The Thermal exhaust is definitely a high-quality exhaust. It came complete and color coordinated for driver and passenger sides. I would highly recommend them as there exhaust kits doesn’t drone while cruising, and isn’t super loud. A+"

James W. (5/5)

Perfect for the Explorer ST

"Lives up to the hype. Easy, straight forward install. Nice growl with zero drone, and not overly aggressive until you stomp on the gas pedal. The cold start is a little louder than expected, which I like (my wife not so much)."

Rick B. (5/5)

Great exhaust!

"I swapped to this exhaust from the AWE 3” exhaust because with aftermarket high flow cat downpipes it started to drone really bad after a year. It was super annoying on road trips and with family. Glad I swapped to the Thermal 2. 5” and wish I would have started out with it."

Lee H. (5/5)

"This thing sounds great and is waaaay better than stock from a sound, aesthetic and functional perspective. The team was great and kept me informed during the build"

Chris (5/5)

2. 5 catback

"Exhaust went on perfectly no issues. Not too loud for the wife. Sounds great!"

john v. (5/5)

Perfect Exhaust

"Love the 2. 5inch paired with Cvf DPs. has just the right tone for daily needs. Cold start and WOT sound amazing. No drone, and highway speeds i notice nothing. Went together nicely, no issues with fitment or alignment. Very Happy."
