Rattle on my sportex exhaust

[kronk10]

Hi my sportex full system never rattled when i had it fitted but when the car is warmed up after about a month of driving around with the sportex on its rattling on idle. When the revs are sitting just below 1000 rpm it rattles and stops when the revs hit 1000 rpm or over. When i hold the exhaust or move it with my hand it stops. Can someone help it isnt touching anything that i can see cus i have no ramp so what the hell is it:confused:
its doing my head in i have tried to put up with it but i just cant

When mine is idling, the dash,mirrors etc vibrate slightly.
It stops once you raise the revs to above idle.
I guess its something to do with the noise from the exhaust, as it didn't use to do it with my std exhaust fitted.

yea as soon as i fitted my sportex i heard a rattle but my standard was fine. I really cannot put my finger on it. It must be when the exhaust is warm cus iam sure when hot they expand or summit like that
