Best used at Gas stations , Prior to leaving Dinner , Garage while neighbors are outside.
I'm still waiting to get my C63s coupe next month and trying to figure out a few possible options. Does your tune make the Performance exhaust button obsolete? Can you close the valves with that button??

My hottest 93 octane tune has more pops and burbles than normal but valves work just like stock.
My other 2 tunes allow normal/stock exhaust sound /function incase I don't want to sound too rowdy.
