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

I have a 2018 Ford Mustang Gt with BBK long tube headers and an H pipe these mufflers made this car sound amazing if you’re looking for that hard American muscle sound these mufflers right here is a must. Hopefully one day, hopefully we can work together. Check me out on YouTube DailyDrivenStangs
