We ran my 07 550i with only headers (after pulling out the OEM exhaust manifolds) for a very short period of time just to see how loud it was. There were no cats or exhaust installed. It was quite loud. Sounded like a race car and you could feel the idle in your chest if you got close to the car. Crazy.
