Strange Noise On Acceleration

[Micro]

Hey guys,

Really pleased so far with the new wheels, have a little niggle that's developed now though.

On acceleration (or just revving the engine), when it's heated up to temperature, past 3000rpm it sounds as if somethings vibrating.

I'm guessing perhaps exhaust / heat shield? (if I open the drivers door when i'm parked up at home it sounds a lot louder as if it's coming from under the car). It still pulls strong and at motorway speeds I don't seem to hear it.

Cheers,

Tom

Just an update - took it back to the garage I bought it from, they're dealing with it as the catalytic converter that's broken down inside, and so that's being replaced under warranty.
