This is honestly how the 2025 ST should’ve come from the factory. It’s only loud on a cold start, then quickly settles into a smooth, mild growl that sounds just right. Under normal driving you can definitely hear the exhaust now—but in a good way. It’s not overpowering, just clean and refined. Step on it, though… and wow. It comes alive. Best part? This is hands-down the first exhaust I’ve owned that has zero drone, even at highway speeds. Huge win. We daily drive this with my wife and two toddlers, and everyone agrees it sounds great and stays perfectly comfortable. Meanwhile, when I put my heavier foot to work, it delivers exactly the sound I want when accelerating. Install was super simple and straightforward. Watching Houston Speed Freaks’ install video made it a breeze—only took a couple of hours tops. Overall, I couldn’t be happier. Zero regrets and would absolutely recommend this to anyone on the fence.

I was kind of in the dark on shipping status as far as logging onto the account but they sent email when it shipped.

Fast shipping and great price for such good quality

As my first ever exhaust mod purchase and installation i've done, the process has been so simple. It made my car sound even better and louder, but also quiet enough for cruising. Overall, highly recommend to integra owners and beginner modders. The installation was fun and straight forward. Really happy with this purchase!

2. 5 Exhaust perfect

UPS takes forever !!!

Great shipping time

Perfect sound for my Maverick 2. 0T love it

Super easy to install, only took 3 hours even with my very limited mechanical skill! Love the sound! I was worried it would be too loud for my daily driver but it’s subtle unless you want to be loud! Very happy about no extra charge for the black tips!

Great price and shipped quickly! The fit and finish is exactly what you would expect from thermal and the sound is great too.

Shipped in two days fit perfect sound great

Thermal R&D is hands down the BEST sound, BEST build quality, and the BEST company to work with. They care so deeply about their product quality, listening to their customers and put out an outstanding product. 10 out of 5 Stars, and trust me, if you’re reading this you found your spot for some bad A$& products. Must buy for sure!

Its winter time here in PA not good picture or video weather.
