This is a very common issue in vitz. Hold the silencer (when its not hot) and you'll notice that the sound is gone.It's due to a loose silencer bolt.My friend's vitz had the very same issue. I guess that he tightened it and the sound was gone. It's not a very big or serious issue.Go to a workshop from where you can easily access the underbody and then you can locate the exact screw/bolt which is causing this problem.

Ok. Thanks for guidance. I have to visit a silencer repair shop to get silencer nut bolts fixed ?
Np. You're welcome.Yes. Go there but make sure they don't touch anything else. Because it's common practice. Mechanics say sir ye bhi kharab hai ye bhi change kara lo etc etc. Not everyone is like this but people are who do such practice. This has nothing to do with your silencer itself. It's just due to the problem in fitting.
I have this exact same problem, at first i thought it was from fan belt, so i had my fan belt replaced for 5k, butthe noise was still there, later i found out its coming from the silencer
Saad what you did for fixing that sound?
Absolutely nothing, the problem still persist Anyways point being that Vitz have many not-so-serious defects, and this noise from silencer is a quite a common in this model, sorry for not being much of a help
HmmOkOn this Sunday I will get my silencer fix and then will update the results
Just got it fixed yesterday, silencer ki packing ghiss gaye thee, got it replaced for 300rs, and now this noise is gone, packing is some sort of small 2 inch wide metal or ceramic ring
