Exhaust is vibrating. Fix?
When I’m sitting at a stoplight, my car exhaust vibrates. It’s like any knowing clank noise. Other people can hear it around me and sometimes people look at my car. That makes me feel really good about how cool my car looks. Any ideas on what this could be here what is wrong with my exhaust? I have tried looking under the car to see if I can see something wrong but I can’t. It almost sounds like the pipe is a looser fitting is loosening lost system. My gas mileage is also getting worse too. I need to know what do it yourself its for the exhaust. What in the heck could be the wrong with it?
