The NRP Valved Exhaust System for the BMW G30 M550i replaces the factory exhaust from the downpipes back with a full valved catback. The N63 twin-turbo V8 is one of the quietest 500-hp engines on the road from the factory; this system fixes that. With the valves open you get a deep V8 rumble with crackles on overrun, and with them closed the car is as quiet as stock for the commute. Direct bolt-on using the factory mounting points, and 100% reversible.
