I have m330 onboard, despite it already improve the performance and throttle response, this very pipe again impresses me. The same pedaling is now having a noticeable quicker response, also while let go the pedal you can’t ignore that the car idles and glides smoother. Highly recommend for every ST owner!
Easy to fit, looks great under the bonnet. Another quality product from Mountune.
Beautiful design by Mountune! Goes well with the Carbon induction kit! Must have if you also want beauty under the hood!
