Sounds awesome! The cold start tone has slightly changed to a deeper tone and driving with the valve open it just sounds perfect. My M235i feels even more alive than ever. Paired with a sports cat and res delete. The delivery was quick and on time considering I’m from the UK. Also love the freebies I received
