If you’ve ever wondered whether it’s worth stepping up to a 3-inch exhaust on your Explorer ST, YouTuber FatGuyBuilds just saved you the guesswork. In his latest install-and-review video, he swaps out his 2.5” Thermal R&D system for the beefier 3” Thermal exhaust on his 2020 Explorer ST - and spoiler alert: the results sound damn good.
Install Notes: A Little Grind, A Lot of Growl
Right off the bat, FatGuyBuilds gets into the install process. Keep in mind, when you’re leveling up to custom gear like this, sometimes it’s worth having a trusted shop or garage handle the job if you're not up for it or don't have the time.

So what benefits were noted after upgrading from the 2.5" to 3" exhaust? The extra diameter gave the system a throatier rumble without crossing into obnoxious territory
The tone of the 3” is much deeper and more pleasant - and no drone at any speed.
That’s what we love to hear. No droning on the highway, no raspy tin can nonsense - just smooth, clean sound thanks to True Helmholtz Technology - Drone Free Exhaust Sound. Here’s the quick rundown:
- Deeper tone with the 3" system.
- Zero drone, even at highway speeds.
- Looks and sounds more aggressive.
- Built in the USA with quality materials.

If you're riding around with a 2.5" Thermal R&D Explorer exhaust system and want an even richer, fuller tone without the drone, the 3" Thermal R&D setup might be exactly what you're after. It’s all about that balance of performance, sound, and daily drivability - plus, it’s backed by Thermal’s reputation for quality and comes with a lifetime warranty.
