C6 weird vibration after exhaust install
Hey guys got a 2005 m6 with a full 3 inch exhaust, this past weekend I installed a 3inch z06 stainless works axle back and drove it home a few hours once I got close to home it developed a vibration that is defiantly noticeably loud but it is intermittent and doesn’t go away under throttle or off. Also once you shut the car off it will continue but not the same way every few minutes it’ll sound like someone’s under neath car pulling on a tire wire and letting it go causing a quick audible and noticeable vibration that can be felt on the floor board. It doesn’t sound like loose pipes as it doesn’t sound like a metal on metal vibration. I’ll be getting it on a lift in two days but I don’t even know where to begin to look. Any ideas would be greatly appreciated

Just ran it over to an exhaust shop and they pointed out it’s hitting after the x pipe before it connects to the axle back it’s touching the body there. Gonna try to take it apart tonight maybe get it to clear
