DC5R buzzing noise

[BlackR]

Hey all, just wondering if any of you had heard this problem. when my car is cool/not warmed up i dont hear anything wrong with it. When my car is warmed up i get a buzzing type noise occur. But i dont get the noise in neutral or when the cluch is pressed in. i only get it when i take off from still, when im accelerating hard, and when i change gears hard. Other ise i dont hear. Any ideas?

It is suppose o be under warranty but honda wollongong wont look at it because i have a HONDATA modified airbox, I was just wondering if anyone knows of a dealer that isnt so picky. And TODA_AU, the noise sounds like an exhaust leak.
