Sounds fantastic- nice deep rumble and very minimal drone when cruising and once you get on the gas, you can hear it sing. 26 explorer ST

No highway drone as promised

10/10

This is without downpipe. Just the exhaust everything else factory. Sounds freaking awesome. Wait until I get the intake and the downpipe. GeezEeee

This 3” Cat back complete exhaust is absolutely amazing. My local shop installed in an hour, fitment was perfect and the sound is thrilling! And zero drone inside. It also solves that terrible stock flex pipe rattle. The 3” upsize lowers the tone perfectly. Very well designed system, highly recommend.

Amazing!

Just had mine installed recently, picked the car up today and had a 2 hour drive home from the RST Speedhaus. I could hear myself think! My car has an S280 turbo and Airtec manifold so it’s pretty rowdy. The old exhaust I had droned terribly but with this setup there is barely any drone now. The quality of the material and the sound you get from this system is top notch. This system makes the fiesta sound like a properly tuned 4 banger. Quiet when commuting, grin inducing when wide open.

Excellent quality and shipping was very fast.

Great product fast shipping

Process was easy from buying to installing. Thanks again!

Great sounding exhaust, zero drone; what every self respecting adult who still wants to enjoy their ride is looking for…and free shipping helps.

Very fast shipping, system was packaged very securely to eliminate damage during shipping, excellent quality system, all parts needed were included, no modifications were necessary, professional installer stated that even he was impressed with the level of quality!

Install and sound is perfect came quick.

Good

When I installed the first version of the 2025+ exhaust I was very impressed with the fit and quality of the parts. The sound outside the truck was very good, not raspy or popping like some 4 cyl exhausts are. Most of the sound inside the truck was good also, there was just a little too much resonance at part throttle between about 1650 and 1950 rpm, where my truck spends a lot of time around town. When I heard about the newer design rear section I decided to try it. I'm so glad I did!! This exhaust is now exactly what I was looking for, a nice lower tone that's not annoying at low or part throttle - but still gives a great performance sound when you're having a little fun :) I've read where some people mentioned loss of ground clearance, but that doesn't appear to be an issue on my truck. Kudos to Thermal R&D for the redesign and taking care of the customer.

2. 5 in is just enough on the st explorer.

Love your product

Great experience. Responsive, professional, and buying direct was by far the most cost effective option shipped to Arkansas.

Excellent service. Was informed the high order count would cause a delay but it only took about 8 additional days. Received order and shipped the old C-Section back the next day. Great sound, zero drone - a lot less than stock.

Very good experience. Would do business with them again.
