GRAIL exhaust system for BMW M4/M3 with selectable tailpipes in stainless steel or black

  • 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 drive an imported vehicle with an operating license, please find out before purchasing whether you need the exhaust system to be entered in your vehicle documents.

    Loud – maximum volume

    You drive 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 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 gas 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 designed not only for maximum sound output when the flaps are open, but also for maximum attenuation when the flaps are closed.

    If you drive your vehicle within the respective test ranges, your GRAIL is no louder than the standard system. The highest quality and materials are how we achieve the unmistakable delta between loud and quiet, which has been unparalleled for years.

    Flow

    Your GRAIL has been developed in such a way that the exhaust gas flow is minimally affected. A major improvement over the series system is a given thanks to a larger pipe diameter and reduction in tapers. Your GRAIL does not get in the way of the exhaust gas.

    Solid

    Our stainless steel flaps made of CNC-milled solid material switch in the prescribed measuring ranges depending on the model and thus allow the perfect combination of back pressure reduction and extreme volume from pure engine sound.

    Quality made in Germany

    With a GRAIL you get what you have always been looking for. The highest processing quality using the best materials in combination with the maximum possible sound for your vehicle.
