I have found one real drawback to loud exhaust. When you are going through a Wendys or McDonalds drive through line you have to keep shutting your motor off out of respect for others trying to order at the speakers. It becomes start and move ahead a car length, then shut it off. Then restart and move another car length. It also causes some delays because pretty often someone will get out of their car to take a picture with their cell phone.
