Waterlocks collect the cooling water present in the exhaust system when the engine is stopped, to prevent drainage back into the engine.
In addition,they have great sound-dampening capabilities, and act as a very efficient muffler. The size of the waterlock is not only determined by the diameter of the exhaust hose, but also by the quantity of water that must be collected. A long exhaust run will require a larger waterlock.
