    ABS pipe flames at a low temp and can be toxic so you can try, but be very careful.

    PVC conduit does bend easier with just a heat gun. I wouldn't use an open flame on PVC or ABS.

    Go to stacey davids gearz web site ask there. They will know the situation.

    I haven't tried bending ABS but have bent 2" PVC conduit by heating it.

    You can buy flexible PVC which would be my preference for an intake attached to an engine. The vibration and movement of the engine on the flexible mounts is likely to put large forces on a rigid connection.

    If your engine needs a snorkle then you must have an intersting task to make the electrical system work under water.

    If it is ABS drain pipe, it probably has a foam core. I never tried bending it. But, I suspect that the foam core could cause problems when bending.

    Use the flex pipe, and don't try to bend the ABS

    For a snorkel you need a smooth interior wall and gradual bends to keep restriction at a minimum. The flexable pipes are all corrigated that I have seen, they will not work for his application so don't recommend it unless it is smooth and minimum restriction.

    The flex PVC you'll find used in spas and swimming pools has a smooth inside wall.
