metallic sound

[mikeltang]

i have a 318is and when i accelerate my car makes a metallic noise which seems to be coming from the exhaust. at first i thought it was the muffler which was a POS can the previous owner threw on. well i replaced the muffler and the metallic sound is still there and i have no idea what it is. the cat looks new so i dont think thats the problem, any ideas on what it might be? thanks in advanced - mike

exhaust leaks, loose exhaust hangers, and hit the exhaust with a rubber mallet to try to reproduce the sound if its not an exhaust leak.
