Gave Up!! ### 1/5 — App works but *2024-04-02, version 2.2.6* App working fine, but Thor exhaust sometime automatically turn on when I’m not inside vehicle and some sound not working. I’m with new refreshed model S ### 1/5 — So frustrating *2023-10-21, version 2.2.6* I have had a Thor system installed and despite my best efforts the app fails to open once it’s recognised the control module. The sounds work when using the switch but without being able to use the app it’s pretty useless. Such a shame. ### 1/5 — Not connected *2023-09-06, version 2.2.6* Can’t find Bluetooth to connect. ### 1/5 — Delay when car starts *2020-12-13, version 2.0.2* Since the new update there’s a big delay from the start till the speakers make the noise ### 1/5 — The application is buggy *2020-01-24, version 2.0.0* The application has alot of bugs . Im trying to add new sound packs some works and some do like the Audi rs7 and jingle bell . It transfers me to the apple pay and i can’t download . And the in app purchase is bad . It force you to pay by apple pay while our country doesn’t has apple pay . So any new sound package i will not able to buy it . ### 2/5 — Poor support, minimal instructions. Flawed execution *2025-09-23* No shifting sounds so it’s only good up to 30mph then it’s just becomes an annoying whine that doesn’t sound realistic. Off throttle there is no decel sounds it just cuts volume and isn’t authentic. Fun at idle and for slow driving but once up to speed because it doesn’t include shifts and build revs again I just turn it off above 30mph. I was hoping it would be nice to leave in and have a realistic sound. Pretty disappointed in the whole experience for the high expense. Poor customer support as well during install. ### 2/5 — Not happy *2021-12-18, version 2.0.9* Will be much better if there was to be more pops and bangs otherwise your car just sounds like a 1.2 corsa with a cherry bomb exhaust Will appreciate it if you update the system Thank you ### 4/5 — Great service *2023-04-13, version 2.2.5* In first month speaker got dead but company replaced for new one , after nearly year control device burned out ( was old version square box) Thor replaced for new model with not any problems . So looks like some of them are faulty but with that kind of service no make any difference. It’s very hard to spot car sound like diesel tbh even in garage or Mot they thought it’s v8 lol ### 5/5 — Mari *2024-09-16* I put the tor system on my diesel BMW, the car finally sounded cool! I'm just delighted with the functionality of this thing, especially the jokes with the boombox function! As for installing all the previous ones quickly and without problems, this thing is not visible in any way, thanks to the guys for their device! Because I didn't have to mount a complex exhaust and I can always turn off the system directly from my Apple Watch and drive in silence in the evening in the yard, for example! **Developer response:** Thank you for your feedback. We are glad you liked everything, we hope the system will continue to be a pleasure to drive. We wish you a pleasant drive and a loud exhaust💥 ## Most praised reviews (6 highest-rated) ### 5/5 — Added an Alpine 2ohm 300w amp *2023-04-01, version 2.2.5* I’ve got the 2 speaker set up, but it wasn’t loud enough. So added an Alpine amp to the system now sounds amazing! The Thor amp is really weak, but the speakers are capable of a lot more. I strongly suggest anyone that has the set up to get an amp! ### 5/5 — Wow *2020-08-24* So, it was first experience for me:)) I decided on this for a long time, and now I am already with my new clothes for my car, now many drivers flinch when I start driving 😄 I will continue to try this system, I recommend everyone who loves variety ### 5/5 — Excellent experience *2020-08-23* I have excellent experience of using that system. If you want to change sound of vehicle exhaust you should try that thing. Totally recommend. ### 5/5 — AMAZING!!! *2020-08-23* I got THOR system on my Infinity QX50. Don’t get me wrong but stock exhaust sounds like nothing, now I got perfect exhaust sound!!! It’s amazing!!! Very easy to install and easy for use! App works from cell phone and Apple Watch. ### 5/5 — If you are in Miami - Read this *2020-08-23* I have a diesel and it has been frustrating for me because I have been looking for something that can change and improve my exhaust note. After a long and dedicated search, I found a Thor distributor in Miami and ever since I’ve been in contact, he has been dedicated to get me these awesome exhaust. If you are in South FL and have a Diesel, Hybrid or Battery car, consider Thor! ### 5/5 — Works better than I thought *2020-08-09* I was so excited about this system and now My Lexus ES300 Hybrid is a muscle car with V8 under the hood. I’m shocked as well as everyone else around. The App works perfect so far and I can choose a car on my Apple Watch 😍 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
