Grail exhaust system for VW Golf 7 GTI 3-inch

Grail exhaust system VW GOLF 7GTI 3-inch

Loud but Legal

GRAIL flap exhaust systems with ECE type approval can be used on your EU vehicle without registration. They are made by hand in Germany from high-quality L304 stainless steel and produce an unmistakable sound that will give you goosebumps the first time you start the engine.
If you are driving an imported vehicle with an operating license, please find out 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 enables maximum volume and wonderful engine sound outside the test areas, because only in these 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 specially developed silencers, which are developed and adapted for your vehicle in the GRAIL sound laboratory. The combination with solid flaps is not only designed 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 not be louder than the standard system. The highest quality and materials allow us to achieve the unmistakable delta between loud and quiet, which has been unrivalled for years.
