hi Everyone

for a few weeks my car was vibrating very lightly on low rpm, low gear and on neutral. I figured out that thew exhaust flexi that might be the problem. I went under my car and shook with my hand all the exhaust pipe from front to back to see if anything is loose. In the front part the flexi that is moving when i shook it. I pretty sure the vibration comes from there. The exhaust hanging rubbers are fine.

There are two flexi, one is normal looking and the other one is little gold. I have attatched photo. the gold one is in the drivers side. Can anyone tell me if this is the problem. The engine mountings are fine please help thanks
