So what exactly comes in the box when you order an exhaust from Thermal R&D Performance? Joe at Lethal Performance just dropped an epic unboxing and review video to show you - this time showcasing Thermal's 3-inch exhaust system for the Ford Explorer ST. If you're craving a deeper rumble and a big boost in performance, this setup should be on your shortlist.

What's In The Box? Thermal R&D Exhaust Complete Kit

Thermal's Ford Explorer exhaust is a standout. The included components are not just well-designed, they're targeted to address some common issues Explorer ST owners may be familiar with. Here's a list of the components, and what makes them special:

Replacement Flexpipes/Midpipes: One of the biggest issues Explorer ST owners face is the notorious OEM flexpipes and midpipes that tend to fail prematurely. Thermal has solved that headache by including robust replacements right in the kit. It’s an instant upgrade and future-proofing in one smooth move.

Mid-Muffler/Rear Mufflers and Tailpipes: Thermal uses T304 stainless steel, which stands up to corrosion. Additionally, our muffler systems incorporate our Drone Free True Helmholtz Technology to get rid of that annoying buzz.

Full Mandrel Bends: Our system is fully mandrel bent - these bends aren't just fancy - they’re critical to optimal exhaust flow. This translates into increased horsepower, reduced back pressure, and an overall better-sounding and performing ride.

Ultimately, this system here is all custom made and overall the welds on it are absolutely gorgeous … you can definitely tell this is a Thermal piece rather than anybody else's.

Easy, OEM Mount Installation: Not all aftermarket exhausts are created equal, and anyone who's spent hours cutting or welding to fit one knows it. Thermal sidesteps this hassle with precision-engineered systems that bolt right onto OEM mounts - no welding, no cutting, just clean and easy. All clamps needed come with the kit.
