I used a handheld propane torch and a red hot throwaway knife. Cut through it like butter, with a pretty clean edge. The only issue I ran into is after I'd put the bumper cover back on, the black plastic top piece that sits over the snorkel didn't fit quite right, making it impossible to put the pop pin back in the headlight. So I carefully softened up the plastic piece with the torch and molded it down onto the snorkel. Not a big issue, and I love the way it looks!
