What bush?

Jay guys my car is eating exhaust bushes I've Tryed  standard ones they last a couple off months if that I spent lot of money on poly ones and they melted in 10 min WTH. So any advice would be great but the way running full sport exhaust 2.5" on 2.0 16v with r1 carbs . Thanks people 

Dam your exhaust must be getting hot if its melting hangers!! 

You can get metal ones but they don't offer any movement for the system when you go over bumps. 
Maybe heat wrap the mounting arm bits before putting the rubbers on.
