I just raised mine up about a foot. I used rubber couplers and plastic tubing. I used bailing wire to keep it off the exhaust and rapped aluminum foil around it a few times to keep it from melting. This is just temporary until I do full snorkels, but has lasted almost a year. I plan to use flexible intake hose from Auto Zone when I snorkel. I've used it before. It can handle heat pretty well and is flexible enough to route away from the exhaust.
