Loud but Legal

GRAIL valve exhaust systems with ECE type approval can be used on your EU vehicle without registration. They are made of high-quality L304 stainless steel, handcrafted in Germany, it produces a distinctive sound that will give you goosebumps the first time you start your engine.
If you are driving an imported vehicle with a vehicle registration certificate, please check before purchasing whether you need to have the exhaust system registered in your vehicle documents.

Loud – maximum volume

You ride your GRAIL loud but legally.

With the intelligent control you get the legal maximum out of your engine sound.

The use of highly effective silencers allows for maximum volume and wonderful engine sound outside of the test areas, because only in these areas are the flaps of your GRAIL closed and only when closed is the rear silencer part of the exhaust flow.

This is how we achieve pure engine sound and maximum volume.

Your GRAIL can also be quiet.

With a GRAIL you get two vehicles in one.

We use custom-developed mufflers, which are developed and customized for your vehicle in the GRAIL sound lab. The combination with solid flaps is designed not only for maximum sound output when the flaps are open, but also for maximum damping when the flaps are closed.

If you drive your vehicle within the respective test ranges, your GRAIL will be no louder than the stock system. Using the highest quality and materials, we achieve the unmistakable delta between loud and quiet that has been unparalleled for years.
