Rattly rear box

[JonnyCJ]

Got a bit of a rattle in my QPV rear box. It's a standard QPV albeit with Sport options fitted from the factory.

Question is, do the standard QPV exhausts have a valve in them that opens up under increased exhaust pressure or was that just the Sport GT's ?

Thanks

No valves in the Pre- 2009 cars

Hmm - that's what I thought, do they have anything mechanical in them at all ? Being advised that they do.
