Ford Authority Tests the Thermal R&D Exhaust on Steeda’s 2025 Ford Explorer ST
For many Ford Lovers the factory exhaust note on an SUV like the 2025 Ford Explorer ST leaves a lot to be desired. Ford Authority’s Alex Luft of the MOTROLIX Channel recently got behind the wheel of Steeda’s 2025 Ford Explorer ST demonstrator vehicle to put its aftermarket upgrades through the paces. The star of the show from an audible standpoint was undeniably the Thermal R&D Performance cat-back exhaust system.
If you’re tired of the muffled, factory-restricted exhaust tone of your ST, check out Alex's review for the perfect blueprint for waking up your SUV’s twin-turbo powertrain.
Ditching the Tame Explorer ST Stock Sound
Explorer ST owners and modders frequently complain about Ford's decision to pipe artificial engine noise into the cabin through the speakers to compensate for a quiet exterior exhaust note:
“The stock system is it's a bit tame. It it does have a little bit of a kind of a kick to it from a from an audible standpoint, but I wouldn't really describe it as being loud or all that noticeable.” - Alex Luft
With the Thermal R&D system installed, the difference is immediate. Upon cold start, the exhaust is the very first thing you hear - a genuine, aggressive mechanical growl (and a REAL one!) that gives the ST a true presence - something that lets you know it's definitely not stock.
While the cabin remains insulated from overwhelming noise, the exterior sound is a complete game-changer. When you step on the gas and hit wide-open throttle, the real exhaust note takes over.
"This thing will turn heads just on sound alone." - Alex Luft
Be sure to stick around for the last 45 seconds of the video, which features some awesome rev sounds that perfectly demonstrate the deep, aggressive exhaust note this system produces.
Aggressive Sound When You Want It
Perhaps the most critical concern for any exhaust upgrade on a family-hauling SUV is cabin drone. You want an aggressive growl when you put your foot in it, but you don't want a headache-inducing hum when cruising down the interstate with the family.
“I am very happy to report that on the highway, there is no drone from the exhaust system - you're going 70/80 mph down the highway, down the interstate - you're not going to get any drone. You can have a normal conversation in the vehicle without raising your voice.” - Alex Luft
The cabin remains quiet at cruising speeds because of the expert craftsmanship by the experts at Thermal R&D Performance. We have decades of experience in creating premium exhaust systems using True Helmholtz Technology for an exhaust note that is actually drone free.
