MThe 440i G22 Coupé and G23 Convertible with the B58 engine is the answer for everyone who wants more sound – no registration required, no compromises. Thanks to ECE type approval, the system is registration-free within the EU and therefore ready to drive immediately. Handcrafted in Germany from L304 stainless steel.\u003c\/p\u003e\n\u003cp\u003eThe B58 engine of the MThe 440i has the potential for a rich six-cylinder sound – the GRAIL exhaust system brings out exactly what BMW doesn't allow from the factory. A full, raw inline-six sound under load, without any interference with the factory exhaust valve control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLoud but Legal:\u003c\/strong\u003e The GRAIL uses the factory BMW exhaust flap control system of your vehicle. MThe system is compatible with the 440i and behaves exactly as BMW specifies from the factory. At higher engine speeds and under load, the valves open fully – then the system delivers the full GRAIL sound. Since the valves are controlled exclusively via the factory system, the system complies with all ECE regulations and is fully street legal.\u003c\/p\u003e\n\u003cp\u003eFLOW DOWN® is an official GRAIL partner in the Ruhr area and specializes in the professional installation of exhaust systems.
