peugeot 206 exhaust?

Hi i was wondering if you could give me a little advice.
My peugoet 206 sounds like a tank everytime i start the engine.
The noise is comming from the front of the car and it seems to be getting worse everyday.
Its even staring the rattle now.
I had a mate of mine come over to have a look but we still cant find th source of the problem.
So any help would be greatly appreciated
