For those who installed Hartge Exhaust System.. Can you please tell the difference from the oem exhaust? for example when starting the engine? while driving? Or if you can post some videos let us hear the sound of the car.. I really found the M5 so muted, which i think its bit annoying when you come to say its an M car..
Last night when i was at MB showroom the sales man i know told me to start the engine and when he heard the sound he told me is it a diesel!! i told him no its not.. i reved the car and then he noticed the engine sound.. he told me that it doesnt have the roar of AMG cars..
