Feedback on GruppeM fitted on Turbo-charged cars

[Ahbengdriver]

dear MCF-ers,

 

for those of you who had fitted the GruppeM on your TC cars, can I ask if there is any noticeable improvement in performance, or is it just a piece of useless decor with perhaps some audio entertainment and when rev your engine.

 

This thing looks nice, not cheap though.

 

Kam sia!
