I drive a Vitz 2005 1.0ltr and just past few days I noticed a very heavy sound coming from the silencer. I think it seems to be coming from the dholki somewhere. Please note No CAT conv. Is in place so there was a heavy noise but it was not this unpleasant to hear just now the car is making a heavy growl although while driving the car seems to be running smooth. I asked a mechanic and he said to get checked from a silencer shop.
Question is any good silencer shops near the Bahria Town/PWD Pindi area, really don't want to drive down all the way to Saddar or Islamabad for this issue?
