Sudden banging / knocking from exhaust......

[bearne1]

.........was driving up a dual carriageway and was driving near rev limit. Heard a sudden knocking banging which I am assuming was the exhaust (Janspeed full system).

Had new rear mounts and centre mount in the last 2 months. Puzzled, thought the sound was more underneath than rear but not 100% sure!

Took it into local Protyre and one of my rear exhausts mounts was shot so likely the exhaust movement is causing this. They found slight metal to metal contact from the manifold to the subframe but dogmount seemed in good order. Wondering if it is worth replacing the bushes in this to reduce this noise or is it likely the engine has moved slightly causing a smaller gap? I have had the RS Tuner remap and wondering if this may have had an affect?

Thanks

Dogbone mount improves the car so if it was me id get that done.

remap wont have made a difference

And not the increase in rev limit from 6750 (i think) to 7500? Spoke to a Renault Tech yesterday (he has owned 13 RS Clio's) and said that the increase in rev limit may have slightly moved the engine and top mount may need adjusting?

Thoughts?

May just upgrade dogbone bushes but will see how it goes. After replacing shot rear mount with one from Renault it seems to have stopped!
