Replacing an exhaust mount

[darrenw]

Since late last year I've noticed a knocking coming from the rear-left of the car when cold or when going over uneven roads, but not potholes,

This week I've finally had the combination of time and weather to have a proper look on the ramps.

 

All the suspension parts are tight with no bushing loose/work and all shields tight. Giving the rear box a thumping, I've found that if there is lateral movement the pipe hits the down stand for the plastic tray. Up or down and it's silence. Relief that I've found it as it was driving me nuts.

I'm thinking of replacing the rubber hanging mounts to see if that resolves it. 

Are there any after market mounts that are better than the OEM. Looked at the Febi ones but curious if that are better before I did out the lube?
