@Hassan1991. Visited the silencer workshop. The guy told that the silencer is not in bad shape and could be repaired and will work for the decent period of time as the local made silencer wont last too long. so I have repaired that. Total labor cost Rs 400/-
Now everything looks good. Silencer sound back to its normal. when i was before ......
Take Care Will ask further for the help if needed.
Jazakallah.
