Just picked up an E60 M5. It has the section 3 Meisterchaft. Can anybody tell me what section 3 is? I've heard of sections 1 and 2 but never of 3. I definitely want my car louder already. Too civil for my taste. Does anybody know what i can do to make it louder without spending $3,000 for an exhaust. Sooner or later i'll get one, but at the moment i'm not ready to pay that price.
