Has a valve system exhaust and resonator delete which adds a deep tone to exhaust and amplifies shifting noise. However a separate button can turn it silent if need be (still have old back box and resonator) Perfect for someone looking for speed and cheap running costs, Beautiful colour with two tone alcantara interior extremely comfortable and unique. Bought from BMW Full service history and health check was performed at the time of the buy. Runs perfectly with no issue. Harmon kardon speaker, Heated steering wheel front and rear sensors with lane departure warning and collision detection. Sad to sell it however looking for an upgrade. 10/10 would recommend!
