Few days ago my car exhaust pipe broken so I went to a Silencer wala and he said k "jaali choke hai is liyay pipe toot gaya" but I cant get what jaali he is talking about I confirmed from him whether he is calling Cat Converter a jaali but this time he had no clue what I was saying so I simply got the broken part of the pipe welded and returned. But till now I am figuring out that Jaali???
