Sounds like diff bushes. Easiest way to check is to get it on a ramp, get someone to go through the gears and go on to do throttle whilst you stand underneath and see what's going on.

Amongst a many things not already mentioned it could be diff hop due to knackered rear sub frame bushes.

I think you guys are probably right. The diff bushes were replaced last year with superpro bushes however the ear mounts are shit. They are just little packers designed to sit inside the oem bush to aid stiffening it and i didnt think they actually fit that well. Im going to remove them on Saturday and see if that cures it. I also need to have a look at the diff backlash and see if thats excessive

i dont think its the exhaust unless there is something new near it, its solid that exhaust.

 

The car is prone for smashing diffs, i did one on cadwell and one on the road, i may have done another but i cant recall.

 

what your describing to me is not what ive had with the diff going, when the diff goes it will grind under hard acceleration or click and tick.
