The picture that Pinkpanther has posted is that of Rasim's Vitara, he used 2.5 inch sanitary pipe for making the snorkel, cost of material was Rs.300 only and he paid 500 to the mechanic. On the other hand, if you import a genuine Safari snorkel, it will cost you between 25000 and 35000 i.e. depnding on the make and model of the vehicle.
If you have extra money or are brand contionus, for Safari snorkel you can contact Mr. Aleem 0300-9444172. Mr. Aleem and his partner are the importors of ARB products in Pakistan, which in adition to Safari, include Oldman EMU shocks as well.
