support bracket for J pipe?
 

I have 'modified' my GHL headers since I had the engine out. I dont need the heat box and managed to remove another 5kg of weight for my track machine by chopping the boxes off. But now I realise they were dual function in that one of them was supporting the J pipe to some extent. Now it vibrates rather badly on idle. I am struggling to find anywhere useful to brace it too.
Has anyone solved this problem?
Thanks
