Engine mount

[mad306man]

Hi all

Having a minor problem with my 2001 hdi estate, when I pull away or I floor it in 2nd, the decat pipe bangs the subframe. If I put poly mounts on the exhaust to stop it, the downpipe separates from the turbo elbow an the exhaust blows.

So I'm thinking the engine is moving too much, are my engine mounts on their way out?

Is there one particular mount that is responsible for this excess movement?

I'm thinking the lower gearbox mount but but could do with some confirmation

Cheers
