If you’re a Ford Explorer ST enthusiast, this sound show-down and Thermal exhaust review from Tyler Clark (@LessEcoMoreBoost) is for you. Check out this comparison between two different Explorer ST setups to see how they stack up in the sound department.

Explorer ST Sound Comparison: The Setup

Tyler's video features two Ford Explorer STs. The first one is Tyler's, equipped with CV Fab downpipes and a Thermal R&D 3-inch exhaust system. The second Explorer belongs to his neighbor, Eric, and it’s completely stock - no modifications - except for a drop-in filter. But here’s the twist: Tyler is going to install the same Thermal R&D 3-inch Ford Explorer exhaust on Eric’s stock Explorer - to see how the sounds compare.

Ford Explorer ST Exhaust Sound Test

First, let’s talk about the stock setup. With the factory exhaust, Eric’s Explorer ST is pretty quiet. It’s got that smooth, subdued tone you’d expect from a stock SUV. But once they swap out the OEM exhaust for the Thermal R&D 3-inch system, things get a lot more interesting.

After the installation, they fired up both Explorers to compare the sounds. Here’s the breakdown:

• Eric’s Explorer (Thermal Exhaust): The Thermal exhaust definitely adds a deeper, more aggressive tone. It’s not over-the-top loud and it gives the Explorer a perfect level of muscular sound. If you’re looking for an upgrade that’s noticeable but not obnoxious, this is a great option.

• Tyler's Explorer (CV Fab Downpipes + Thermal Exhaust): The custom downpipes paired with the Thermal exhaust make the sound is even more pronounced. There’s a deeper growl and a slightly more aggressive note. It’s the kind of sound that turns heads when you hit the gas.

The Verdict: Both Sound Amazing

So, which setup sounds better? Honestly, both sound fantastic. The Thermal R&D exhaust system delivers a huge sound improvement no matter what. If you’re keeping your Explorer ST mostly stock but want a deeper, more aggressive tone, the Thermal exhaust alone will do the trick. Looking for that extra growl and a more performance-oriented sound? Consider modding your exhaust even further.

One thing’s for sure: Thermal R&D exhaust systems are a step above the rest. Thanks to our Drone Free True Helmholtz Technology, they reduce drone while delivering a rich, powerful sound. Whether you’re cruising down the highway or revving at a stoplight, you’ll love the way your Explorer ST sounds.

Final Thoughts

Upgrading your exhaust is one of the easiest Explorer ST performance mods out there. Whether you go with a straight Thermal R&D exhaust or pair it with additional mods, you’re in for a treat. Both setups sound incredible, so it really comes down to how much of a statement you want to make.

When you’re ready to take your Explorer ST’s sound to the next level, the Thermal R&D 3-inch exhaust is among the best exhausts for Explorer ST. Thermal R&D was started in the 80's, and over the years we've developed our True Helmholtz Technology, offering actual Drone Free Exhaust Sound that essentially eliminates drone.
