GRAIL 3.5-inch Valve Exhaust System + EQL Option
suitable for BMW M4 F8x

The BMW M4 F8x is an uncompromising track tool – its 3.0-litre inline-six biturbo (S55) ranks among the sharpest engines of its era. Our GRAIL 3.5-inch Valve Exhaust System unleashes the full sonic potential of the S55: precise, intense, and with the edge that defines a true M car. Thanks to the optional EQL upgrade, you can personalise the sound experience even further.
