im looking to change my rear exhaust silencer as its damaged and worn thourgh on the side

so anyone recommend a aftermarket one or should i stay with the original silencer

don tknow what aftermarket ones are available but i d fit an original and fit the straight through internal pipe. sandifords sell them, i think it is a from a crf450 and you cut it to length. made a noticeable power difference i thought, especially if you de coke the rest of the system. check the bush set up where it is attached and renew with the correct washers - there will be play but enough so that when the tyre touches it moves and shouldnt wear through over time

I'd stick with the original one, I have the WES one on mine and just think its a bit too crackly for my taste.
