Thor Active Sound System A sporty engine sound without modifying your exhaust

A Mustang with a four-cylinder turbo instead of a 5.0 V8? To many purists, it borders on heresy.And yet, the 2.3 EcoBoost has its own logic. 290 horsepower, lively handling, finally affordable taxes and controlled fuel consumption. This is the Mustang that lets you live the myth on a daily basis, without putting your budget on the line.Except that one detail remains, one that nobody can pretend to ignore. When you drive a Mustang, you expect to hear a Mustang…

In 2023 Lotus launched the Eletre. A hyper-SUV weighing more than 2.5 tonnes, fully electric, technologically spectacular. A brilliant car in many respects. But also, by its very nature, completely silent. For the brand's purists, that silence is more than a detail. It is a fundamental question about what made the soul of Lotus.The owner of this Eletre, a former Exige driver, approached the car with exactly that nuance. He embraced his transition to electric driving, but he was not willing to give up the sensory identity that had always drawn him to Lotus. Here is how a Thor Level 2 + Echo Kit reconciled the two.

Park a BMW i8 Roadster anywhere and watch what happens. The butterfly doors opening towards the sky, the futuristic supercar silhouette. Within seconds, every head turns and the car becomes the centre of attention.Then the engine starts. And that is where the deal breaks down. This spectacular machine, looking like a prototype that has escaped from a motor show, springs to life with a surprisingly civilised purr. A three-cylinder petrol engine paired with an electric motor. Technically impressive. Emotionally frustrating.The owner of this i8 Roadster wanted to fix that last imbalance. Here is how a Thor Level 4 Kit finally gave the car a sound to match what it is.

The owner of this stunning Porsche Taycan Turbo wanted to bring back presence and character to his electric vehicle, without compromising its design or performance.

The BMW 6 Series GT (G32) is an elegant, comfortable and refined car to drive. However, for many enthusiasts, it sometimes lacks one essential element of driving pleasure: real sound presence.

The Mercedes C-Class is known for its comfort, elegance and premium build quality. On this model, we installed a Thor Level 4 system to transform the driving experience, without modifying the engine or the original exhaust.

The owner of this BMW 550d G30 contacted us with a simple request: “make audible what the engine already hides”. Here’s how a Thor Level 2 kit completely transformed his driving experience, without modifying a single mechanical component.

Driving a Porsche Cayenne means embracing a paradox. On one hand, the Stuttgart crest, a rich motorsport heritage, and the promise of raw driving emotion. On the other, a comfortable, versatile SUV designed to cover long distances in near silence.But a Porsche should be heard. It should have a voice — and that’s exactly what we gave it with the Thor Active Sound system.

The BMW X5 F15 commands respect. Its imposing silhouette, massive grille, and stance as a large German SUV give it an immediate presence on the road. Visually, it never goes unnoticed.But… only visually, because when it comes to sound, the X5 doesn’t quite live up to expectations.The owner of this X5 wanted his vehicle to be heard as much as it is seen.

The Mercedes GLS is a rolling monument. Nearly five metres long, seven seats, a cabin as hushed and refined as an S-Class, and a six-cylinder diesel engine that delivers its power with almost unsettling discretion.But a flagship deserves a voice.Here is how a Thor Level 4 kit was installed on this GLS 350d.

Let’s be honest: choosing a 330i instead of an M3 is not a compromise. In many cases, it’s the smartest decision.Lower taxes, cheaper insurance, better fuel consumption, proven reliability and real everyday comfort. On paper and in real life, the 330i wins almost every rational argument.Except one. And it comes back at every start, every acceleration, every weekend drive. That’s the one thing this installation was designed to fix: the sound.

Diesel cars are very practical and efficient. This is what everybody loves them for. Especially if it is a family crossover. 

When you take delivery of a BMW X5, the first months are all about discovery. You explore the technology, fine-tune the seat position, test the driving modes and enjoy the feeling of a new car.But after two or three years, something changes. The owner knows the car inside out. He understands exactly what it delivers, and more importantly, what it doesn’t. And at that point, one question keeps coming back: “Why can’t I hear anything when I accelerate?”The owner of this 2023 X5 contacted us three years after purchasing it.

There is a category of BMW 5 Series owners that rarely gets talked about. Those who cover 40,000, 50,000, sometimes 70,000 kilometres a year. Executives on the road, business owners, senior sales managers. For them, the car is not a weekend hobby: it is a rolling office.The 530d ticks every box for this profile: diesel range, comfort, reliability, image. On paper, it is the perfect car for this kind of use.But after two or three years spending more time behind the wheel than at a desk, many of them notice the same thing: the car has become too transparent. Here is why this installation changed everything.

Picture the scene. You are sitting at a red light. Behind you, a sportive rumble. You glance in the rear-view mirror expecting to see an AMG, an RS or an M — and instead, a large family van pulls up.That is exactly what the owner of this Mercedes V-Class wanted to achieve. A practical everyday car that becomes something unexpected the moment you press the accelerator. Here is how a Thor Level 2 Kit turned this diesel van into one of the most surprising vehicles on the road.

Choosing an Audi Q7 over a BMW X5 or a Mercedes GLE is rarely a coincidence. It is usually the choice of a very specific vision of premium motoring: less ostentatious, more precise, almost silent in the way it asserts its presence.Audi has always embraced this philosophy of discretion. The problem is that by refining this identity so much, the brand has also softened what once made its legendary Quattro models feel alive. Here is how a Thor Level 2 kit gave this diesel Audi Q7 its voice back, without betraying the elegance that makes it so distinctive.
