I have been thinking about adding the pulleys to my e46 M3. May have to pull the trigger on that one.

Thank you and be safe over there. Also, let me know if you need anyone to drive the M until you return. I can make sure the battery is charged up and the seals stay lubricated if you want? :D

OMG it sounds like a Viper in that clip.

And of course I must include my favorite sound of all time:
