Land Rover can be partially submerged in water; how (if at all?) does the exhaust system differ from other exhaust engineering to prevent damage?
Land Rover Exhaust Systems
I don't think there is any difference with the exhaust system; Just do no not release the accelerator once the exhaust is submerged, otherwise you will suck water into the engine, which is not a good idea. And a snorkel is so that oxygen can get to the engine, when it is submerged; I've never heard of one that expels exhaust fumes.
It isn't a big deal. All you have to do is keep your revs high enough to help keep water out. In most cases, water fording will require higher revs anyway, and you will generally be in a lower gear for instant power if needed, so it isn't normally a problem. Even if this doesn't work out properly, and you do get water in the exhaust system, the vehicle can still run. I have managed to start my Rover with a flooded exhaust before, while it was still sitting in the water. They just don't mind it all that much, in the end. It isn't really a problem. It is the intake you should be worried about, and electronics. Neither are really much of an issue on Rovers if you are fording the water properly. Military vehicles have the raised exhaust systems sometimes for many reasons. It isn't required for fording, but the larger the exhaust pipe, the less pressure builds up to keep out water. Military vehicles are diesel, and tend to have very large low pressure exhaust systems. As well, the vehicles just aren't sealed up all that well, they don't provide good throttle modulation, and they have to be soldier-proofed. In such cases, it is generally best just to raise the exhaust outlet to avoid any potential issues, even if they are not likely.
