I like the quietness of the M5 for daily driving but occasionally I'll run the car in a local road rally in the non-competitive section. Then the car is too quiet!
Is there a quick and inexpensive way to make the car's exhaust louder that won't hurt the car and can be quickly and easily reversed? (I don't want to spend a fortune as I'll update the car soon anyway.)
