206 engine vibration

Hello friends again. 206 My 2004 model automatic car with tube. While waiting for the first start and then at idle, the noise comes from the exhaust and the vehicle vibrates as if something is knocking on something. Could it be a motor or transmission wedge. Be a helper

Sir, hold the end of the exhaust, which is likely to be made from exhaust, shake it. I also had the same problem, it was making a loud sound, I changed the muffler lifetime completed, it improved

But it shakes the car or something, it does not come out with little ice in the sound or it goes like a carpa carpa. My exhaust burns right, but it sounds like a better quality problem :)
