Suzuki Mehran 2006 exhaust silencer

[yaseen.abbas1989]

Hi to Everyone

I have a 2006 model MehanVX, recently there was some work like engine seals were broken, piston cleaning new rings were installed and also installed a new gasket but the white smoke issue is still there and my mechanic says that in the car exhaust pipe carbon is still there and when the pipe will heat this carbon will burn and the white smoke issue will be resolved.
My question is how to wash the exhaust pipe?
Is it safe to put a water pipe in the exhaust and clean it with water?
Or there any other way to clean the pipe.

White smoke usually means hesd gasket is weak but u said u replaced the gasket.The carbon in the exhaust doesn't make sense.Get it checked by another mechanic.I don't think that work has been done properly.
