We had to stop due to traffic ahead. I have to say I was really surprised and so was the driver of the M5. We had a chance to talk at the next light and he couldn't get over that he couldn't hear my car. The stock 550 exhaust is so quiet.
Tsk..Tsk..Street racing??? On a public road???
We do not condone such behavior! It must be the Dinan mod's effect on your right foot. Hope it is not contagious..I get my car back from its Dinan flash on Wed! LOL
Thanks for the report!
